<a href="#props">properties</a> 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
<vue-autosuggest ...>
  <template slot="before-input"> content before the <input /> goes here </template>
  <template slot="after-input"> content after the <input /> goes here </template>
  <template slot="before-suggestions"> content before the <ul> goes here </template>
  <template slot="before-section-<section.name e.g. 'default'>"> section header content for specific section goes here </template>
  <template slot="after-section-<section.name e.g. 'default'>"> footer content goes here for specific section. </template>
  <template slot="after-section"> Default footer content for all sections </template>
  <template slot="after-suggestions"> content after the <ul> goes here </template>
</vue-autosuggest>
```

### Adding labels

It is common in forms to add a label next to the `<input />` tag for semantic html / accessibility. You can use the 
`before-input` slot to accomplish this in conjunction with the `inputProps.id`:

```html
<vue-autosuggest ...>
  <template slot="before-input">
    <label :for="inputProps.id">Search here:</label>
  </template>
  ...
</vue-autosuggest>
```

### suggestion item (i.e. default slot)
Used to style each suggestion inside the `<li>` 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
<vue-autosuggest>
  <template slot-scope="{suggestion}">
    <!-- suggestion.name corresponds to which section the item is in -->
    <div v-if="suggestion.name === 'blog'">
      <!-- suggestion.item corresponds to the suggestion object -->
      <a target="_blank" :href="suggestion.item.url">{{suggestion.item.value}}</a>
    </div>
    <div v-else>{{suggestion.item}}</div>
  </template>
</vue-autosuggest>
```

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

| :----------- | :------- | :------: | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `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.                                                                                                                                                                                                                                                                                                                                                                     |
| `limit`      | Number   |          | Limit each section by some value. Default: `Infinity`                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

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);
        }
    }
}
```

<a name="renderSuggestion"></a>

### renderSuggestion

This function can be used to tell vue-autosuggest how to render the html inside the `<li>` 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 <div style={{ color: "red" }}>{suggestion.name}</div>;
},
```

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);
},
```

<a name="getSuggestionValue"></a>

### getSuggestionValue

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

```js
getSuggestionValue(suggestion) {
    return suggestion.item.name;
},
```

<a name="shouldRenderSuggestion"></a>

### 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 `<input />` so vue-autosuggest will use any DOM event you pass it for listening. This is implemented using `v-on:<event>`. |
| `@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`
