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 '@mail2gowthamganesan/vue-treeselect'
  // import the styles
  import '@mail2gowthamganesan/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',
          // control checkbox show/hide
          checkBox: false,
          children: [ {
            id: 'aa',
            label: 'aa',
          }, {
            id: 'ab',
            label: 'ab',
          } ],
        }, {
          id: 'b',
          label: 'b',
        }, {
          id: 'c',
          label: 'c',
        } ],
      }
    },
  }
</script>

Browser Compatibility

Chrome

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.
