### Dependencies

1. [AngularJS](https://angularjs.org/) - v1.3.8

2. [jQuery](http://jquery.com/) - v1.11.1

3. [Lo-Dash](https://lodash.com/) - v2.4.1

4. [Bootstrap](http://getbootstrap.com/) - v3.3.1

###Demo

[Example](http://alexpechkarev.github.io/angular-ui-select/)

###Usage

How does it work? Simple. Directive tells compiler to attached specific behaviour and create drop-down element from template. 

To start, ensure all above dependencies are included as well as `ui-select.js` directive and `selectCrt.js` controller.

Add HTML markup for select element first

```html

    

    

```

Following attributes bind data with controller scope:

 `data="selectData"`   - drop-down data 

 `single="selectedItem"`  - selected element by default

 `update="setSelected(select.box,item)"` - specify selected element by given drop-down list

 `close="removeSelect(select.box)` - remove given drop-down list

In the `selectCrt.js` initialise data for select element and specify selected item :

```javascript

  $scope.selectData = [

      {id:'0',  name: 'Select product type', shade:''},

      {id:'123',name:'black',  shade:'dark'},

      {id:'245',name:'white',  shade:'light'}     

  ];

 $scope.selectedItem = $scope.selectData[0]; 

```

Three methods in controller respond to user behaviour:

1. Add new drop-down list

2. Get value of selected element

3. Remove drop-down list

1) To add a new drop-down list `addSelect()` method has to be triggered, in this example it's a button click. This method adds new item (select box) to an array. Having unique counter helps referring to a specific drop-down list when retrieving / updating values or removing drop-down list from array of elements.

```javascript

  $scope.selectGroup = [];

  $scope.box = 0;

  $scope.addSelect = function() {

    $scope.selectGroup.push({box:$scope.box});

    $scope.box++;

  };

```

2) Responding to select behaviour method `setSelected()` obtains or updates selected value from drop-down list. In this example default value is omitted. Single value per drop-down list will be stored in array of selected values, on changed event it's value will be updated accordingly. [Lo-Dash](https://lodash.com/) library utilised to manage selected values in array. 

```javascript

  $scope.setSelected = function (index,item) {

      

      if(item.shade !== ""){

      

        $scope.currentItem = item;

      

        if(!_.find($scope.allItems,{'index':index}) ){

            $scope.allItems.push({index:index,item:item});

        }else{

            _.remove($scope.allItems, function(it) { return it.index === index; });

            $scope.allItems.push({index:index,item:item});

        }

      

      }

        

  };

```

3) To remove drop-down list method `removeSelect()` respond to this action. Selected value from given drop-down list being removed from array of values first and then drop-down list being removed it's self.

```javascript

  $scope.removeSelect = function(box){

      

       $scope.currentItem = [];

       _.remove($scope.allItems, function(it) { return it.index === box; });

      if(_.find($scope.selectGroup,{'box':box}) ){

          _.remove($scope.selectGroup, function(it) { return it.box === box; });

      }

  };

```
