vue-multiselect

The most complete selecting solution for Vue.js, without jQuery.

Current version: 1.1.4

For Vue 2.0 users:

Vue-multiselect 2.0-beta is available: npm install vue-multiselect@next. API changes:

Instead of Vue.partial for custom option templates you can use a custom render function.
The :key props has changed to :track-by, due to conflicts with Vue 2.0.
Added support for v-model
@update has changed to @input to also work with v-model
:selected has changed to :value for the same reason

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)

Install & basic usage

npm install vue-multiselect

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

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

Alternatively:

<script src="https://cdn.jsdelivr.net/vue.multiselect/1.1.4/vue-multiselect.min.js"></script>

VueMultiselect will be available on the window object. As it contains a default export you have to access it through VueMultiselect.default.

// register the plugin globally
Vue.component('Multiselect', VueMultiselect.default)

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

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

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

multiselect(
  :options="source",
  :selected="value",
  :close-on-select="true",
  @update="updateValue",
  placeholder="Select one",
  label="name",
  key="name"
)

Multiple select with search

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

Tagging

with @tag event

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"
)

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

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"
)

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
  }
}

<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

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.

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