## Installation
```bash
composer require lavary/laravel-menu
```
If you are in Laravel 5.5 you won't need to edit your `config/app.php`, if you are in a previous version of Laravel, please do the following:
Append Laravel Menu service provider to `providers` array in `config/app.php`.
```php
'providers' => [
/*
* Laravel Framework Service Providers...
*/
Illuminate\Foundation\Providers\ArtisanServiceProvider::class,
Illuminate\Auth\AuthServiceProvider::class,
Illuminate\Broadcasting\BroadcastServiceProvider::class,
...
Lavary\Menu\ServiceProvider::class,
...
],
```
At the end of `config/app.php` add `'Menu' => Lavary\Menu\Facade::class` to the `$aliases` array:
```php
'aliases' => [
'App' => Illuminate\Support\Facades\App::class,
'Artisan' => Illuminate\Support\Facades\Artisan::class,
...
'Menu' => Lavary\Menu\Facade::class,
],
```
This registers the package with Laravel and creates an alias called `Menu`.
To use your own settings, publish config.
```bash
php artisan vendor:publish --provider="Lavary\Menu\ServiceProvider"
```
## Getting Started
You can define the menu definitions inside a [laravel middleware](http://laravel.com/docs/master/middleware). As a result anytime a request hits your application, the menu objects will be available to all your views.
```bash
php artisan make:middleware GenerateMenus
```
Be sure to also add the middleware to the `app\Http\Kernel.php`
```php
protected $middlewareGroups = [
'web' => [
//...
\App\Http\Middleware\GenerateMenus::class,
],
//...
];
```
Open the middleware you just created `app\Http\Middleware\GenerateMenus.php`
Then add a basic menu declaration. For example:
```php
public function handle($request, Closure $next)
{
\Menu::make('MyNavBar', function ($menu) {
$menu->add('Home');
$menu->add('About', 'about');
$menu->add('Services', 'services');
$menu->add('Contact', 'contact');
});
return $next($request);
}
```
Finally, open a view and add:
```php
{!! $MyNavBar->asUl() !!}
```
Your menu will be created and displayed on the page.
**Note:** `$MyNavBar` is just a hypothetical name used in these examples; You may name your menus whatever you please.
In the above example `Menu::make()` creates a menu named `MyNavBar`, Adds the menu instance to the `Menu::collection` and ultimately makes `$myNavBar` object available across all application views.
This method accepts a callable inside which you can define your menu items. `add` method defines a new item. It receives two parameters, the first one is the item title and the second one is options.
The second parameter, `options`, can be a simple string representing a URL or an associative array of options and HTML attributes which we'll discuss shortly.
You can use `Menu::exists()` to check if the menu already exists.
```php
Menu::exists('primary'); // returns false
Menu::make('primary', function(){});
Menu::exists('primary'); // returns true
```
You can use `Menu::makeOnce()` to ensure the make callback is only called if a menu by the given name does not yet exist. This can be useful if you are creating the same menu in multiple places conditionally, and are unsure whether other conditions have caused the menu to be created already.
```php
Menu::makeOnce('primary', function(){}); // Creates primary, and executes callback.
Menu::makeOnce('primary', function(){}); // No operation.
```
**To render the menu in your view:**
`Laravel-menu` provides three rendering methods out of the box. However you can create your own rendering method using the right methods and attributes.
As noted earlier, `laravel-menu` provides three rendering formats out of the box, `asUl()`, `asOl()` and `asDiv()`. You can read about the details [here](#rendering-methods).
```php
{!! $MyNavBar->asUl() !!}
```
You can also access the menu object via the menu collection:
```php
{!! Menu::get('MyNavBar')->asUl() !!}
```
This will render your menu like so:
```html
```
And that's all about it!
## Routing
#### URLs
You can simply assign a URL to your menu item by passing the URL as the second argument to `add` method:
```php
$menu->add('About Us', 'about-us');
```
#### Named Routes
`laravel-menu` supports named routes as well:
This time instead of passing a simple string to `add()`, we pass an associative with key `route` and a named route as value:
```php
// Suppose we have these routes defined in our app/routes.php file
//...
Route::get('/', ['as' => 'home.page', function(){...}]);
Route::get('about', ['as' => 'page.about', function(){...}]);
//...
// Now we make the menu:
Menu::make('MyNavBar', function($menu){
$menu->add('Home', ['route' => 'home.page']);
$menu->add('About', ['route' => 'page.about']);
});
```
#### Controller Actions
Laravel Menu supports controller actions as well.
You will just need to set `action` key of your options array to a controller action:
Suppose we have these routes defined in our `routes/web.php` or the older `app/Http/routes.php` file:
```php
Route::get('services', 'ServiceController@index');
```
Then to refer to this route, we can pass the action into the options array.
```php
$menu->add('services', ['action' => 'ServicesController@index']);
```
**Additionaly:** if you need to send some parameters to routes, URLs or controller actions as a query string, you can simply include them in an array along with the route, action or URL value:
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Home', ['route' => 'home.page']);
$menu->add('About', ['route' => ['page.about', 'template' => 1]]);
$menu->add('services', ['action' => ['ServicesController@index', 'id' => 12]]);
$menu->add('Contact', 'contact');
});
```
#### HTTPS
By default, the HTTP vs HTTPS will be determined by Laravel's UrlGenerator which matches the current schema of the page.
If you need to overwrite this behavior, call `secure()` on the item's `link` attribute to force https. Alternatively add key `secure` to the options array and set it to `true`:
```php
$menu->add('Members', 'members')->link->secure();
// or alternatively use the following method
$menu->add('Members', ['url' => 'members', 'secure' => true]);
```
The output as `
- ` would be:
- Members
- #
- #
- Separated Item
-
*
* - Another Separated Item
-
* ...
* - Separated Item
-
*
* ...
* - Item's Title
-
* About
*- Another Plain Text Item
*
*
* -
About
- hasChildren()) class="dropdown" @endif>
{!! $item->title !!}
@if($item->hasChildren())
@endif
- hasChildren()) class="dropdown" @endif data-test="test">
{!! $item->title !!}
@if($item->hasChildren())
@endif
- hasChildren()) class="dropdown" @endif data-test="test" @lm_endattrs>
{!! $item->title !!}
@if($item->hasChildren())
@endif
- ...
```html
...
...
```
## Sub-items
Items can have sub-items too:
```php
Menu::make('MyNavBar', function($menu){
//...
$menu->add('About', ['route' => 'page.about']);
// these items will go under Item 'About'
// refer to about as a property of $menu object then call `add()` on it
$menu->about->add('Who We are', 'who-we-are');
// or
$menu->get('about')->add('What We Do', 'what-we-do');
// or
$menu->item('about')->add('Our Goals', 'our-goals');
//...
});
```
You can also chain the item definitions and go as deep as you wish:
```php
$menu->add('About', ['route' => 'page.about'])
->add('Level2', 'link address')
->add('level3', 'Link address')
->add('level4', 'Link address');
```
It is possible to add sub items directly using `parent` attribute:
```php
$menu->add('About', ['route' => 'page.about']);
$menu->add('Level2', ['url' => 'Link address', 'parent' => $menu->about->id]);
```
## Set Item's ID Manually
When you add a new item, a unique ID is automatically assigned to the item. However, there are time when you're loading the menu items from the database and you have to set the ID manually. To handle this, you can call the `id()` method against the item's object and pass your desired ID:
```php
$menu->add('About', ['route' => 'page.about'])
->id('74398247329487')
```
Alternatively, you can pass the ID as an element of the options array when adding the menu item:
```php
$menu->add('About', ['route' => 'page.about', 'id' => 74398247329487]);
```
## Set Item's Nickname Manually
When you add a new item, a nickname is automatically assigned to the item for further reference. This nickname is the camel-cased form of the item's title. For instance, an item with the title: `About Us` would have the nickname: `aboutUs`.
However there are times when you have to explicitly define your menu items owing to a special character set you're using. To do this, you may simply use the `nickname()` method against the item's object and pass your desired nickname to it:
```php
$menu->add('About', ['route' => 'page.about'])
->nickname('about_menu_nickname');
// And use it like you normally would
$menu->item('about_menu_nickname');
```
Alternatively, you can pass the nickname as an element of the options array:
```php
$menu->add('About', ['route' => 'page.about', 'nickname' => 'about_menu_nickname']);
// And use it like you normally would
$menu->item('about_menu_nickname');
```
## Referring to Items
You can access defined items throughout your code using the methods described below.
#### Get Item by Title
Use $menu followed by the item's title in *camel case*:
```php
$menu->itemTitleInCamelCase
// or
$menu->get('itemTitleInCamelCase')
// or
$menu->item('itemTitleInCamelCase')
```
As an example, let's insert a divider after `About us` item after we've defined it:
```php
$menu->add('About us', 'about-us')
$menu->aboutUs->divide();
// or
$menu->get('aboutUs')->divide();
// or
$menu->item('aboutUs')->divide();
```
If you're not comfortable with the above method you can store the item's object reference in a variable for further reference:
```php
$about = $menu->add('About', 'about');
$about->add('Who We Are', 'who-we-are');
$about->add('What We Do', 'what-we-do');
```
#### Get Item By Id
You can also get an item by Id if needed:
```php
$menu->add('About', ['url' => 'about', 'id' => 12]);
$about = $menu->find(12)
```
#### Get All Items
```php
$menu->all();
// or outside of the builder context
Menu::get('MyNavBar')->all();
```
The `all()` method returns a *Laravel Collection*.
#### Get the First Item
```php
$menu->first();
// or outside of the builder context
Menu::get('MyNavBar')->first();
```
#### Get the Last Item
```php
$menu->last();
// or outside of the builder context
Menu::get('MyNavBar')->last();
```
#### Get the Active Item
```php
$menu->active()
// or outside of the builder content
Menu::get('MyNavBar')->active();
```
#### Get Sub-Items of the Item
First of all you need to get the item using the methods described above then call `children()` on it.
To get children of `About` item:
```php
$aboutSubs = $menu->about->children();
// or outside of the builder context
$aboutSubs = Menu::get('MyNavBar')->about->children();
// or
$aboutSubs = Menu::get('MyNavBar')->item('about')->children();
```
`children()` returns a *Laravel Collection*.
To check if an item has any children or not, you can use `hasChildren()`
```php
if( $menu->about->hasChildren() ) {
// Do something
}
// or outside of the builder context
Menu::get('MyNavBar')->about->hasChildren();
// Or
Menu::get('MyNavBar')->item('about')->hasChildren();
```
To get all descendants of an item you may use `all`:
```php
$aboutSubs = $menu->about->all();
```
#### Get the Parent of the Item
First get the item using one of the methods above then call `parent()` on it.
To get the parent of `About` item
```php
$aboutParent = $menu->about->parent();
// or outside of the builder context
$aboutParent = Menu::get('MyNavBar')->about->parent();
// Or
$aboutParent = Menu::get('MyNavBar')->item('about')->parent();
```
To check if an item has a parent or not, you can use `hasParent()`
```php
if( $menu->about->hasParent() ) {
// Do something
}
// or outside of the builder context
Menu::get('MyNavBar')->about->hasParent();
// Or
Menu::get('MyNavBar')->item('about')->hasParent();
```
#### Magic Where Methods
You can also search the items collection by magic where methods.
These methods are consisted of a `where` concatenated with a property (object property or even meta data)
For example to get an item with parent equal to 12, you can use it like so:
```php
$subs = $menu->whereParent(12);
```
Or to get item's with a specific meta data:
```php
$menu->add('Home', '#')->data('color', 'red');
$menu->add('About', '#')->data('color', 'blue');
$menu->add('Services', '#')->data('color', 'red');
$menu->add('Contact', '#')->data('color', 'green');
// Fetch all the items with color set to red:
$reds = $menu->whereColor('red');
```
This method returns a *Laravel collection*.
If you need to fetch descendants of the matched items as well, Just set the second argument as true.
```php
$reds = $menu->whereColor('red', true);
```
This will give all items with color red and their decsendants.
## Referring to Menu Instances
You might encounter situations when you need to refer to menu instances out of the builder context.
To get a specific menu by name:
```php
$menu = Menu::get('MyNavBar');
```
Or to get all menus instances:
```php
$menus = Menu::all();
```
You can also call `getCollection()` to get the same result:
```php
$menus = Menu::getCollection();
```
Both methods return a *Laravel Collection*
## HTML Attributes
Since all menu items would be rendered as HTML entities like list items or divs, you can define as many HTML attributes as you need for each item:
```php
Menu::make('MyNavBar', function($menu){
// As you see, you need to pass the second parameter as an associative array:
$menu->add('Home', ['route' => 'home.page', 'class' => 'navbar navbar-home', 'id' => 'home']);
$menu->add('About', ['route' => 'page.about', 'class' => 'navbar navbar-about dropdown']);
$menu->add('services', ['action' => 'ServicesController@index']);
$menu->add('Contact', 'contact');
});
```
If we choose HTML lists as our rendering format like `ul`, the result would be something similar to this:
```html
```
It is also possible to set or get HTML attributes after the item has been defined using `attr()` method.
If you call `attr()` with one argument, it will return the attribute value for you.
If you call it with two arguments, It will consider the first and second parameters as a key/value pair and sets the attribute.
You can also pass an associative array of attributes if you need to add a group of HTML attributes in one step; Lastly if you call it without any arguments it will return all the attributes as an array.
```php
//...
$menu->add('About', ['url' => 'about', 'class' => 'about-item']);
echo $menu->about->attr('class'); // output: about-item
$menu->about->attr('class', 'another-class');
echo $menu->about->attr('class'); // output: about-item another-class
$menu->about->attr(['class' => 'yet-another', 'id' => 'about']);
echo $menu->about->attr('class'); // output: about-item another-class yet-another
echo $menu->about->attr('id'); // output: id
print_r($menu->about->attr());
/* Output
Array
(
[class] => about-item another-class yet-another
[id] => id
)
*/
//...
```
You can use `attr` on a collection, if you need to target a group of items:
```php
$menu->add('About', 'about');
$menu->about->add('Who we are', 'about/whoweare');
$menu->about->add('What we do', 'about/whatwedo');
// add a class to children of About
$menu->about->children()->attr('class', 'about-item');
```
## Manipulating Links
All the HTML attributes will go to the wrapping tags(li, div, etc); You might encounter situations when you need to add some HTML attributes to `` tags as well.
Each `Item` instance has an attribute which stores an instance of `Link` object. This object is provided for you to manipulate `` tags.
Just like each item, `Link` also has an `attr()` method which functions exactly like item's:
```php
Menu::make('MyNavBar', function($menu){
$about = $menu->add('About', ['route' => 'page.about', 'class' => 'navbar navbar-about dropdown']);
$about->link->attr(['class' => 'dropdown-toggle', 'data-toggle' => 'dropdown']);
});
```
#### Link's Href Property
If you don't want to use the routing feature of `laravel-menu` or you don't want the builder to prefix your URL with anything (your host address for example), you can explicitly set your link's href property:
```
$menu->add('About')->link->href('#');
```
## Active Item
You can mark an item as activated using `active()` on that item:
```php
$menu->add('Home', '#')->active();
/* Output
*
*
*
*/
```
You can also add class `active` to the anchor element instead of the wrapping element (`div` or `li`):
```php
$menu->add('Home', '#')->link->active();
/* Output
*
*
*
*/
```
Laravel Menu does this for you automatically according to the current **URI** the time you register the item.
You can also choose the element to be activated (item or the link) in `settings.php` which resides in package's config directory:
```php
'active_element' => 'item', // item|link
```
#### RESTful URLs
RESTful URLs are also supported as long as `restful` option is set as `true` in `config/settings.php` file, E.g. menu item with url `resource` will be activated by `resource/slug` or `resource/slug/edit`.
You might encounter situations where your app is in a sub directory instead of the root directory or your resources have a common prefix; In such case you need to set `rest_base` option to a proper prefix for a better restful activation support. `rest_base` can take a simple string, array of string or a function call as value.
#### URL Wildcards
`laravel-menu` makes you able to define a pattern for a certain item, if the automatic activation can't help:
```php
$menu->add('Articles', 'articles')->active('this-is-another-url/*');
```
So `this-is-another-url`, `this-is-another-url/and-another` will both activate `Articles` item.
#### Disable activation
Sometimes you may need to disable auto activation for single items.
You can pass **disableActivationByURL** in options like this:
```php
$menu->add('Anchor', ['disableActivationByURL' => true, 'url' => '#']);
```
This prevents auto activation by matching URL.
But activation for items with active children keeps working.
## Inserting a Separator
You can insert a separator after each item using `divide()` method:
```php
//...
$menu->add('Separated Item', 'item-url')->divide()
// You can also use it this way:
$menu->('Another Separated Item', 'another-item-url');
// This line will insert a divider after the last defined item
$menu->divide()
//...
/*
* Output as
- :
*
*
* ...
*
*
*
*
*/
```
`divide()` also gets an associative array of attributes:
```php
//...
$menu->add('Separated Item', 'item-url')->divide( ['class' => 'my-divider'] );
//...
/*
* Output as
- :
*
*
* ...
*
*
*
*/
```
## Append and Prepend
You can `append` or `prepend` HTML or plain-text to each item's title after it is defined:
```php
Menu::make('MyNavBar', function($menu){
$about = $menu->add('About', ['route' => 'page.about', 'class' => 'navbar navbar-about dropdown']);
$menu->about->attr(['class' => 'dropdown-toggle', 'data-toggle' => 'dropdown'])
->append(' ')
->prepend(' ');
// ...
});
```
The above code will result:
```html
...
```
You can call `prepend` and `append` on collections as well.
## Before and After
Allows you to add an arbitrary html block instead of a drop-down list. And many other possibilities.
Unlike `append` and `prepend`, `before` and `after` adds an arbitrary html to the root of the tag li.
```php
Menu::make('MyNavBar', function($menu){
$menu->add('User', ['title' => Auth::user()->name, 'class' => 'nav-item'])
->after(view('layouts.pattern.menu.user_info'))
->link->attr([
'class' => 'nav-link dropdown-toggle',
'data-toggle' => 'dropdown',
'role' => 'button',
'aria-expanded' => 'false',
]);
// ...
});
```
Resource of view, pattern: layouts.pattern.menu.user_info
```html
```
The above code will result:
```html
```
## Raw Items
To insert items as plain text instead of hyper-links you can use `raw()`:
```php
$menu->raw('Item Title', ['class' => 'some-class']);
$menu->add('About', 'about');
$menu->About->raw('Another Plain Text Item')
/* Output as an unordered list:
*
* ...
*
*
* ...
*
*/
```
## Menu Groups
Sometimes you may need to share attributes between a group of items. Instead of specifying the attributes and options for each item, you may use a menu group feature:
**PS:** This feature works exactly like Laravel group routes.
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Home', ['route' => 'home.page', 'class' => 'navbar navbar-home', 'id' => 'home']);
$menu->group(['style' => 'padding: 0', 'data-role' => 'navigation'], function($m){
$m->add('About', ['route' => 'page.about', 'class' => 'navbar navbar-about dropdown']);
$m->add('services', ['action' => 'ServicesController@index']);
}
$menu->add('Contact', 'contact');
});
```
Attributes `style` and `data-role` would be applied to both `About` and `Services` items:
```html
```
## URL Prefixing
Just like Laravel route prefixing feature, a group of menu items may be prefixed by using the `prefix` option in the array being passed to the group.
**Attention:** Prefixing only works on the menu items addressed with `url` but not `route` or `action`.
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Home', ['route' => 'home.page', 'class' => 'navbar navbar-home', 'id' => 'home']);
$menu->add('About', ['url' => 'about', 'class' => 'navbar navbar-about dropdown']); // URL: /about
$menu->group(['prefix' => 'about'], function($m){
$about->add('Who we are?', 'who-we-are'); // URL: about/who-we-are
$about->add('What we do?', 'what-we-do'); // URL: about/what-we-do
});
$menu->add('Contact', 'contact');
});
```
This will generate:
```html
```
## Nested Groups
Laravel Menu supports nested grouping feature as well. A menu group merges its own attribute with its parent group then shares them between its wrapped items:
```php
Menu::make('MyNavBar', function($menu){
$menu->group(['prefix' => 'pages', 'data-info' => 'test'], function($m){
$m->add('About', 'about');
$m->group(['prefix' => 'about', 'data-role' => 'navigation'], function($a){
$a->add('Who we are', 'who-we-are?');
$a->add('What we do?', 'what-we-do');
$a->add('Our Goals', 'our-goals');
});
});
});
```
If we render it as a ul:
```html
...
```
## Meta Data
You might encounter situations when you need to attach some meta data to each item; This data can be anything from item placement order to permissions required for accessing the item; You can do this by using `data()` method.
`data()` method works exactly like `attr()` method:
If you call `data()` with one argument, it will return the data value for you.
If you call it with two arguments, It will consider the first and second parameters as a key/value pair and sets the data.
You can also pass an associative array of data if you need to add a group of key/value pairs in one step; Lastly if you call it without any arguments it will return all data as an array.
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Users', ['route' => 'admin.users'])
->data('permission', 'manage_users');
});
```
You can also access a data as if it's a property:
```php
//...
$menu->add('Users', '#')->data('placement', 12);
// you can refer to placement as if it's a public property of the item object
echo $menu->users->placement; // Output : 12
//...
?>
```
Meta data don't do anything to the item and won't be rendered in HTML either. It is the developer who would decide what to do with them.
You can use `data` on a collection, if you need to target a group of items:
```php
$menu->add('Users', 'users');
$menu->users->add('New User', 'users/new');
$menu->users->add('Uses', 'users');
// add a meta data to children of Users
$menu->users->children()->data('anything', 'value');
```
## Filtering the Items
We can filter menu items by a using `filter()` method.
`Filter()` receives a closure which is defined by you.It then iterates over the items and run your closure on each of them.
You must return false for items you want to exclude and true for those you want to keep.
Let's proceed with a real world scenario:
I suppose your `User` model can check whether the user has an specific permission or not:
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Users', ['route' => 'admin.users'])
->data('permission', 'manage_users');
})->filter(function($item){
if(User::get()->can( $item->data('permission'))) {
return true;
}
return false;
});
```
As you might have noticed we attached the required permission for each item using `data()`.
As result, `Users` item will be visible to those who has the `manage_users` permission.
## Sorting the Items
`laravel-menu` can sort the items based on either a user defined function or a key which can be item properties like id,parent,etc or meta data stored with each item.
To sort the items based on a property and or meta data:
```php
Menu::make('main', function($m){
$m->add('About', '#') ->data('order', 2);
$m->add('Home', '#') ->data('order', 1);
$m->add('Services', '#') ->data('order', 3);
$m->add('Contact', '#') ->data('order', 5);
$m->add('Portfolio', '#') ->data('order', 4);
})->sortBy('order');
```
`sortBy()` also receives a second parameter which specifies the ordering direction: Ascending order(`asc`) and Descending Order(`dsc`).
Default value is `asc`.
To sort the items based on `Id` in descending order:
```php
Menu::make('main', function($m){
$m->add('About');
$m->add('Home');
$m->add('Services');
$m->add('Contact');
$m->add('Portfolio');
})->sortBy('id', 'desc');
```
Sorting the items by passing a closure:
```php
Menu::make('main', function($m){
$m->add('About') ->data('order', 2);
$m->add('Home') ->data('order', 1);
$m->add('Services') ->data('order', 3);
$m->add('Contact') ->data('order', 5);
$m->add('Portfolio') ->data('order', 4);
})->sortBy(function($items) {
// Your sorting algorithm here...
});
```
The closure takes the items collection as argument.
## Rendering Methods
Several rendering formats are available out of the box:
#### Menu as Unordered List
```html
{!! $MenuName->asUl() !!}
```
`asUl()` will render your menu in an unordered list. it also takes an optional parameter to define attributes for the `
- ` tag itself:
```php
{!! $MenuName->asUl( ['class' => 'awesome-ul'] ) !!}
```
Result:
```html
```
#### Menu as Ordered List
```php
{!! $MenuName->asOl() !!}
```
`asOl()` method will render your menu in an ordered list. it also takes an optional parameter to define attributes for the `
- ` tag itself:
```php
{!! $MenuName->asOl( ['class' => 'awesome-ol'] ) !!}
```
Result:
```html
```
#### Menu as Div
```php
{!! $MenuName->asDiv() !!}
```
`asDiv()` method will render your menu as nested HTML divs. it also takes an optional parameter to define attributes for the parent `
```php
{!! $MenuName->asDiv( ['class' => 'awesome-div'] ) !!}
```
Result:
```html
```
#### Menu as Bootstrap 3 Navbar
Laravel Menu provides a parital view out of the box which generates menu items in a bootstrap friendly style which you can **include** in your Bootstrap based navigation bars:
You can access the partial view by `config('laravel-menu.views.bootstrap-items')`.
All you need to do is to include the partial view and pass the root level items to it:
```html
...
@include(config('laravel-menu.views.bootstrap-items'), ['items' => $mainNav->roots()])
...
```
This is how your Bootstrap code is going to look like:
```html
```
In case you are using bootstrap 5 (currently in beta) you need to set the `data-toggle-attribute` option from `data-toggle` to `data-bs-toggle` in your `config/laravel-menu/settings.php`.
#### Adding class attributes to child items
Like adding a class to the menu `ul` and `ol`, classes can be added the submenu too. The three parameters to `asUl` are arrays as follows:
- The first array is the attributes for the list: for example, `ul`
- The second is the attributes for the child lists, for example, `ul>li>ul`
- The third array is attributes that are added to the attributes of the `li` element
With this you can add a class to the child menu (submenu) like this:
```php
{!! $menu->asUl( ['class' => 'first-level-ul'], ['class' => 'second-level-ul'] ) !!}
```
## Subset Menus
With your menu constructed you can call any of our subset menu functions to get a new `Builder` to quick generate additional menus.
#### Top Menu
This generates a `Builder` of the top level items, items without a parent.
```php
{!! Menu::get('primary')->topMenu()->asUl() !!}
```
#### Sub Menu
This generates a `Builder` of the immediate children of the active item.
```php
{!! Menu::get('primary')->subMenu()->asUl() !!}
```
#### Sibling Menu
This generates a `Builder` of the siblings of the active item.
```php
{!! Menu::get('primary')->siblingMenu()->asUl() !!}
```
#### Crumb Menu
This generates a `Builder` by recursively getting all of the parent items for the active item (including the active item).
```php
{!! Menu::get('primary')->crumbMenu()->asUl() !!}
```
## Advanced Usage
As noted earlier you can create your own rendering formats.
#### A Basic Example
If you'd like to render your menu(s) according to your own design, you should create two views.
* `View-1` This view contains all the HTML codes like `nav` or `ul` or `div` tags wrapping your menu items.
* `View-2` This view is actually a partial view responsible for rendering menu items (it is going to be included in `View-1`.)
The reason we use two view files here is that `View-2` calls itself recursively to render the items to the deepest level required in multi-level menus.
Let's make this easier with an example:
```php
Menu::make('MyNavBar', function($menu){
$menu->add('Home');
$menu->add('About', ['route' => 'page.about']);
$menu->about->add('Who are we?', 'who-we-are');
$menu->about->add('What we do?', 'what-we-do');
$menu->add('Services', 'services');
$menu->add('Contact', 'contact');
});
```
In this example we name View-1 `custom-menu.blade.php` and View-2 `custom-menu-items.blade.php`.
**custom-menu.blade.php**
```php
```
**custom-menu-items.blade.php**
```php
@foreach($items as $item)
@endforeach
```
Let's describe what we did above, In `custom-menus.blade.php` we put whatever HTML boilerplate code we had according to our design, then we included `custom-menu-items.blade.php` and passed the menu items at *root level* to `custom-menu-items.blade.php`:
```php
...
@include('custom-menu-items', ['items' => $menu->roots()])
...
```
In `custom-menu-items.blade.php` we ran a `foreach` loop and called the file recursively in case the current item had any children.
To put the rendered menu in your application template, you can simply include `custom-menu` view in your master layout.
#### Control Structure For Blade
Laravel menu extends Blade to handle special layouts.
##### @lm_attrs
You might encounter situations when some of your HTML properties are explicitly written inside your view instead of dynamically being defined when adding the item; However you will need to merge these static attributes with your Item's attributes.
```php
@foreach($items as $item)
@endforeach
```
In the above snippet the `li` tag has class `dropdown` and `data-test` property explicitly defined in the view; Laravel Menu provides a control structure which takes care of this.
Suppose the item has also several attributes dynamically defined when being added:
```php
$menu->add('Dropdown', ['class' => 'item item-1', 'id' => 'my-item']);
```
The view:
```php
@foreach($items as $item)
@endforeach
```
This control structure automatically merges the static HTML properties with the dynamically defined properties.
Here's the result:
```
...
...
```
#### Attributes and Callback function of item
When printing a list, you can:
Set the attributes for the list element;
Set the callback function, to add a prefix to each link or by condition ("?id={$id}") and much more.
* **Example of converting a menu into a drop-down list for mobile**
Controller:
```php
$items=[
'copy'=>[
'icon'=>'fa-copy',
'title'=>'Copy',
'text'=>'Copy',
'link_attribute'=>[
'class'=>'nav-link',
'href'=> url(Request::capture()->path()."/copy"),
]
],
];
$controlItem = Menu::make('controlItem', function($menu) use ($items){
foreach ($items as $key => $item) if(!isset($item['visible']) || $item['visible']){
$menu->add($item['text'],['title'=>$item['title']])
->append('')
->prepend(' ')
->link->attr($item['link_attribute']);
}
});
return view('layouts.table.view',[
'controlItem' => $controlItem
]);
```
View: layouts.table.view
```php
asUl(['class'=>'control-items'],[],['class'=>'nav-item']); ?>
```
* **Example of printing the recording management menu**
Controller:
```php
$items=[
'copy'=>[
'icon'=>'fa-copy',
'title'=>'Copy',
'text'=>'Copy',
'link_attribute'=>[
'class'=>'nav-link',
'href'=> url(Request::capture()->path()."/copy"),
]
],
];
$controlItem = Menu::make('controlItem', function($menu) use ($items){
foreach ($items as $key => $item) if(!isset($item['visible']) || $item['visible']){
$menu->add($item['text'],['title'=>$item['title']])
->append('')
->prepend(' ')
->link->attr($item['link_attribute']);
}
});
return view('layouts.table.view',[
'controlItem' => $controlItem
]);
```
View: layouts.table.view (use in a cycle with different IDs)
```php
echo (isset($controlItem)) ? $controlItem->asUl(
['class'=>'dropdown-menu control-item'],
[],
['class'=>'nav-item'],
function($item, &$children_attributes, &$item_attributes, &$link_attr, &$id){
$link_attr['href'] .= "/".(int)$id;
},
$id):'';
```
## Configuration
You can adjust the behavior of the menu builder in `config/settings.php` file. Currently it provide a few options out of the box:
* **auto_activate** Automatically activates menu items based on the current URI
* **activate_parents** Activates the parents of an active item
* **active_class** Default CSS class name for active items
* **restful** Activates RESTful URLS. E.g `resource/slug` will activate item with `resource` url.
* **cascade_data** If you need descendants of an item to inherit meta data from their parents, make sure this option is enabled.
* **rest_base** The base URL that all restful resources might be prefixed with.
* **active_element** You can choose the HTML element to which you want to add activation classes (anchor or the wrapping element).
You're also able to override the default settings for each menu. To override settings for menu, just add the lower-cased menu name as a key in the settings array and add the options you need to override:
```php
return [
'default' => [
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'active',
'active_element' => 'item', // item|link
'restful' => true,
],
'yourmenuname' => [
'auto_activate' => false
],
];
```
**Alternatively**, you can override the default settings with the following methods. Or you can add new custom settings to the menu.
```php
return [
'default' => [
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'active',
'active_element' => 'item', // item|link
'restful' => true,
],
'mysidebar' => [
'active_class' => 'active-class-mysidebar',
],
'mynavbar' => [
'active_class' => 'active-class-mynavbar',
],
];
```
**Example 1:**
Override default settings
```php
Menu::make('MySidebar', function ($menu) {
$menu->options([
'active_class' => 'new-active-class',
]);
$menu->add('Home');
$menu->add('About', 'about');
});
/**
* Results:
[
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'new-active-class'
'active_element' => 'item',
'restful' => true,
]
*/
```
**Example 2:**
Add new settings specific to the menu.
```php
Menu::make('MySidebar', function ($menu) {
$menu->options([
'inactive_class' => 'custom-inactive-class-mysidebar',
]);
$menu->add('Home');
$menu->add('About', 'about');
});
/**
* Results:
[
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'active-class-mysidebar'
'active_element' => 'item',
'restful' => true,
'inactive_class' => 'custom-inactive-class-mysidebar',
]
*/
```
**Example 3:**
Add custom settings and get the rest of the settings from `MySidebar`.
```php
Menu::make('MyNavbar', function ($menu) {
$menu->options([
'inactive_class' => 'custom-inactive-class-mynavbar',
], 'MySidebar'); // or mysidebar
$menu->add('Home');
$menu->add('About', 'about');
});
/**
* Results:
[
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'active-class-mysidebar'
'active_element' => 'item',
'restful' => true,
'inactive_class' => 'custom-inactive-class-mynavbar',
]
*/
```
**Example 4:**
Override all settings (including default settings) and add new ones.
```php
Menu::make('MyNavbar', function ($menu) {
$menu->options([
'active_class' => 'active',
], null);
$menu->add('Home');
$menu->add('About', 'about');
});
/**
* Results:
[
'active_class' => 'active'
]
*/
```
**Example 5:**
Or you can use it like this
```php
Menu::make('MyNavbar', function ($menu) {
$menu->add('Home');
$menu->add('About', 'about');
}, [
'inactive_class' => 'custom-inactive-class-mynavbar',
]);
/**
* Results:
[
'auto_activate' => true,
'activate_parents' => true,
'active_class' => 'active-class-mynavbar'
'active_element' => 'item',
'restful' => true,
'inactive_class' => 'custom-inactive-class-mynavbar',
]
*/
```

We are currently using PSR-2+Symfony formatting. This is easy to implement and check with the [PHP Coding Standards Fixer](http://cs.sensiolabs.org/).
Once you have installed php-cs-fixer and added it to your path, simply run the following command in the laravel-menu folder prior to committing.
```bash
$ php-cs-fixer fix . --rules=@Symfony
```
While everyone has different opinions on formatting, this tool will help provide convenient consistency.
