vue3-treeselect

A multi-select component with nested options support for Vue 3. Thank to riophae and his sources and library for vue 2 taken as basis.

Breaking changes from his library:

property value => modelValue
event input => updated:modelValue
Now use slots with <template>

Features

Single & multiple select with nested options support
Fuzzy matching
Async searching
Delayed loading (load data of deep level options only when needed)
Keyboard support (navigate using Arrow Up & Arrow Down keys, select option using Enter key, etc.)
Rich options & highly customizable
Supports a wide range of browsers (see below)
RTL support

Requires Vue 3.0+

Getting Started

It's recommended to install vue3-treeselect via npm, and build your app using a bundler like webpack.

npm install --save vue3-treeselect

This example shows how to integrate vue3-treeselect with your Vue SFCs.

<!-- Vue SFC -->
<template>
  <div id="app">
    <treeselect v-model="value" :multiple="true" :options="options" />
  </div>
</template>

<script>
  // import the component
  import Treeselect from 'vue3-treeselect'
  // import the styles
  import 'vue3-treeselect/dist/vue3-treeselect.css'

  export default {
    // register the component
    components: { Treeselect },
    data() {
      return {
        // define the default value
        value: null,
        // define options
        options: [ {
          id: 'a',
          label: 'a',
          children: [ {
            id: 'aa',
            label: 'aa',
          }, {
            id: 'ab',
            label: 'ab',
          } ],
        }, {
          id: 'b',
          label: 'b',
        }, {
          id: 'c',
          label: 'c',
        } ],
      }
    },
  }
</script>

If you just don't want to use webpack or any other bundlers, you can simply include the standalone UMD build in your page. In this way, make sure Vue as a dependency is included before vue3-treeselect.

<html>
  <head>
    <!-- include Vue 2.x -->
    <script src="https://cdn.jsdelivr.net/npm/vue@next"></script>
    <!-- include vue-treeselect & its styles. you can change the version tag to better suit your needs. -->
    <script src="https://cdn.jsdelivr.net/npm/vue3-treeselect@^0.1.0/dist/vue3-treeselect.umd.min.js"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vue3-treeselect@^0.1.0/dist/vue3-treeselect.min.css">
  </head>
  <body>
    <div id="app">
      <treeselect v-model="value" :multiple="true" :options="options" />
    </div>
  </body>
  <script>
      createApp({
          data: {
            // define the default value
            value: null,
            // define options
            options: [ {
            id: 'a',
            label: 'a',
            children: [ {
                id: 'aa',
                label: 'aa',
            }, {
                id: 'ab',
                label: 'ab',
            } ],
            }, {
            id: 'b',
            label: 'b',
            }, {
            id: 'c',
            label: 'c',
            } ],
        },
      })
        .component('treeselect', VueTreeselect.Treeselect)
        .mount('#app')

Browser Compatibility

Chrome
Edge
Firefox
Safari

It should function well on IE9, but the style can be slightly broken due to the lack of support of some relatively new CSS features, such as transition and animation. Nevertheless it should look 90% same as on modern browsers.
