For more advanced usage, check out the examples below, and explore the

properties you can use.

## [Slots](#slots)

### header/footer

Slots for injecting content around the results/input. Useful for header/footer like slots or empty state.

```html

   content before the  goes here 

   content after the  goes here 

   content before the 
 goes here 

   section header content for specific section goes here 

   footer content goes here for specific section. 

   Default footer content for all sections 

   content after the  goes here 


```

### Adding labels

It is common in forms to add a label next to the `` tag for semantic html / accessibility. You can use the 

`before-input` slot to accomplish this in conjunction with the `inputProps.id`:

```html

  

    Search here:

  

  ...

```

### suggestion item (i.e. default slot)

Used to style each suggestion inside the `
` tag. Using [scoped slots](https://vuejs.org/v2/guide/components-slots.html#Scoped-Slots) 

you have access to the `suggestion` item inside the `v-for` suggestions loop. This gives you the power of Vue templating, since 

vue-autosuggest does not have an opinion about how you render the items in your list.

```vue

  

    

    


      

      {{suggestion.item.value}}

    

    {{suggestion.item}}

  

```

> This slot will be overridden when the [`render-suggestion`](#renderSuggestion) prop is used.

## [Props](#props)

each section.

| :----------- | :------- | :------: | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| `on-selected` | Function |    ✓     | Determine behavior for what should happen when a suggestion is selected. e.g. Submit a form, open a link, update a vue model, tweet at Ken Wheeler etc.                                                                                                                                                                                                                                                                                                                                                                     |

Below we have defined a `default` section and a `blog` section. The `blog` section has a component

`type` of `url-section` which corresponds to which component the Autosuggest loads. When type is not

defined, Vue-autosuggest will use a built in `DefaultSection.vue` component.

```js

sectionConfigs: {

    'default': {

        limit: 6,

        onSelected: function(item, originalInput) {

            console.log(item, originalInput, `Selected "${item.item}"`);

        }

    },

    'blog': {

        limit: 3,

        type: "url-section",

        onSelected: function() {

            console.log("url: " + item.item.url);

        }

    }

}

```



### renderSuggestion

This function can be used to tell vue-autosuggest how to render the html inside the `
` tag when you do not want to use the 

default template slot for suggestions but would rather have the power of javascript / jsx.

In its most basic form it just returns an object property:

```js

renderSuggestion(suggestion) {

    return suggestion.name;

},

```

But usually it returns a JSX fragment, which is transformed into a virtual node description with babel-plugin-transform-vue-jsx:

```jsx

renderSuggestion(suggestion) {

    return 
{suggestion.name};

},

```

If you're not using babel-plugin-transform-vue-jsx, you can create the virtual node description yourself:

```js

renderSuggestion(suggestion) {

    return this.$createElement('div', { 'style': { color: 'red'} }, suggestion.name);

},

```



### getSuggestionValue

This function will tell vue-autosuggest what to put in the `` as the value.

```js

getSuggestionValue(suggestion) {

    return suggestion.item.name;

},

```



### shouldRenderSuggestions

This function will tell vue-autosuggest if it should display the suggestions popover

```js

/**

 * @param {Array} size - total results displayed

 * @param {Boolean} loading - value that indicates if vue-autosuggest _thinks_ that the 

 *                            the popover should be open (e.g. if user hit escape, or

 *                            user clicked away)

 * @returns {Boolean}

 */

shouldRenderSuggestions (size, loading) {

  // This is the default behavior

  return size >= 0 && !loading

}

```

## [Events](#events)

Below are the list of supported events. `@` is short-hand for 

[v-on](https://vuejs.org/v2/guide/events.html#Listening-to-Events).

| Prop                              | Returns               | Description                                                                                                                                                                 |

| :-------------------------------- | :-------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| `@selected`                       | suggestionItem, index | suggestion select handler. equivalent to sectionConfigs `on-selected` but for all items                                                                                     |

| `@input`, `@focus`, `@blur`, etc. | \*                    | there is a transparent wrapper on the underlying `` so vue-autosuggest will use any DOM event you pass it for listening. This is implemented using `v-on:`. |

| `@opened`, `@closed`              | \*                    | suggestions visibility handler, indicates when the suggestions are opened and closed. This is called alongside [shouldRenderSuggestions](#shouldRenderSuggestions).         |

| `@item-changed`                   | suggestionItem, index | when keying through the results, this event signals which item is highlighted before being selected.                                                                        |

## Browser support

For IE11 and below, some functionality may not work. For example, you will have to manually [polyfill](https://github.com/Financial-Times/polyfill-service/issues/177) `Node.prototype.contains`
