Getting Started

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

npm install --save @nationaljournal/vue-treeselect

This example shows how to integrate vue-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 '@nationaljournal/vue-treeselect'
  // import the styles
  import '@nationaljournal/vue-treeselect/dist/vue-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 vue-treeselect.

<html>
  <head>
    <!-- include Vue 2.x -->
    <script src="https://cdn.jsdelivr.net/npm/vue@^2"></script>
    <!-- include vue-treeselect & its styles. you can change the version tag to better suit your needs. -->
    <script src="https://cdn.jsdelivr.net/npm/@nationaljournal/vue-treeselect@^0.5.0/dist/vue-treeselect.umd.min.js"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@nationaljournal/vue-treeselect@^0.5.0/dist/vue-treeselect.min.css">
  </head>
  <body>
    <div id="app">
      <treeselect v-model="value" :multiple="true" :options="options" />
    </div>
  </body>
  <script>
    // register the component
    Vue.component('treeselect', VueTreeselect.Treeselect)

    new Vue({
      el: '#app',
      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',
        } ],
      },
    })
  </script>
</html>

Browser Compatibility

Chrome
Edge
Firefox
IE ≥ 9
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.
