# vue-multiselect ![Build Status](https://circleci.com/gh/monterail/vue-multiselect/tree/master.svg?style=shield&circle-token=5c931ff28fd12587610f835472becdd514d09cef)
Probably the most complete *selecting* solution for Vue.js, without jQuery.

#### Current version: v1.1.0

### Features & characteristics:
* NO dependencies
* Single select
* Multiple select
* Tagging
* Custom option templates (1.1.0+)
* Dropdowns
* Filtering
* Search with suggestions
* Logic split into mixins
* Basic component and support for custom components
* Vuex support
* Async options support
* \> 99% test coverage
* Fully configurable (see props list below)

## Demo & docs

[http://monterail.github.io/vue-multiselect/](http://monterail.github.io/vue-multiselect/)

## Install & basic usage

``` bash
npm install vue-multiselect
```

``` html
<template>
  <div>
    <multiselect
      :selected="selected"
      :options="options"
      @update="updateSelected">
    </multiselect>
  </div>
</template>
```

``` javascript
import Multiselect from 'vue-multiselect'
export default {
  components: { Multiselect },
  data () {
    return {
      selected: null,
      options: ['list', 'of', 'options']
    }
  },
  methods: {
    updateSelected (newSelected) {
      this.selected = newSelected
    }
  }
}
```

You can now author custom components based on *vue-multiselect* mixins.

``` javascript
import { multiselectMixin, pointerMixin } from 'vue-multiselect'
export default {
  mixins: [multiselectMixin, pointerMixin],
  data () {
    return {
      selected: null,
      options: ['list', 'of', 'options']
    }
  }
}
```

## Roadmap:

* Grouping
* Examples of custom components / templates ready to use in project

## Examples
in jade-lang/pug-lang

### Single select / dropdown
``` jade
multiselect(
  :options="source",
  :selected="value",
  :searchable="false",
  :close-on-select="false",
  :allow-empty="false",
  @update="updateSelected",
  label="name",
  placeholder="Select one",
  key="name"
)
```

### Single select with search
``` jade
multiselect(
  :options="source",
  :selected="value",
  :close-on-select="true",
  :clear-on-select="false",
  @update="updateValue",
  placeholder="Select one",
  label="name",
  key="name"
)
```

### Multiple select with search
```jade
multiselect(
  :options="source",
  :selected="multiValue",
  :multiple="true",
  :close-on-select="true",
  @update="updateMultiValue",
  placeholder="Pick some",
  label="name",
  key="name"
)
```

### Tagging
with `@tag` event
```jade
multiselect(
  :options="taggingOptions",
  :selected="taggingSelected",
  :multiple="true",
  :taggable="true",
  @tag="addTag",
  @update="updateSelectedTagging",
  tag-placeholder="Add this as new tag",
  placeholder="Type to search or add tag",
  label="name",
  key="code"
)
```

```javascript
addTag (newTag) {
  const tag = {
    name: newTag,
    code: newTag.substring(0, 2) + Math.floor((Math.random() * 10000000))
  }
  this.taggingOptions.push(tag)
  this.taggingSelected.push(tag)
},
```

### Custom option template
Using partial API
```jade
multiselect(
  :options="styleList",
  :selected="selectedStyle",
  :option-height="130",
  :custom-label="styleLabel",
  @update="updateSelectedStyle",
  option-partial="customOptionPartial"
  placeholder="Fav No Man’s Sky path"
  label="title"
  key="title"
)
```

``` javascript
import customOptionPartial from './partials/customOptionPartial.html'
Vue.partial('customOptionPartial', customOptionPartial)

// ...Inside Vue component
methods: {
  styleLabel ({ title, desc }) {
    return `${title} – ${desc}`
  },
  updateSelectedStyle (style) {
    this.selectedStyle = style
  }
}
```

``` html
<div>
  <img class="option__image" :src="option.img" alt="No Man’s Sky" />
  <div class="option__desc">
    <span class="option__title">{{ option.title }}</span>
    <span class="option__small">
      {{ option.desc }}
    </span>
  </div>
</div>

```

### Asynchronous dropdown
``` jade
multiselect(
  :options="countries",
  :selected="selectedCountries",
  :multiple="multiple",
  :searchable="searchable",
  @search-change="asyncFind",
  placeholder="Type to search",
  label="name"
  key="code"
)
  span(slot="noResult").
    Oops! No elements found. Consider changing the search query.
```

```javascript
methods: {
  asyncFind (query) {
    this.countries = findService(query)
  }
}
```
