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

<template>
  <div id="app">
    <TreeSelect v-model="value" :multiple="true" :options="options" />
  </div>
</template>

<script setup>
  import { ref } from 'vue';
  import TreeSelect from '@r2rka/vue3-treeselect'
  import 'vue3-treeselect/dist/style.css'
  
  const value = ref(null);
  const options = [ 
      {
        id: 'a',
        label: 'a',
        children: [{
          id: 'aa',
          label: 'aa',
        }, {
          id: 'ab',
          label: 'ab'
        }]
      },
      {
        id: 'b',
        label: 'b',
      },
      {
        id: 'c',
        label: 'c',
      }];
</script>

    <template #option-label="{ node, shouldShowCount, count }">
      <div>{{ node.id }} {{ shouldShowCount }} {{ count }}</div>
    </template>

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.
