How to use it:

1. Install and import the library.

import Vue from 'vue';
import VueCascaderSelect from 'vue-cascader-select';

2. Register the Cascader Select.

Vue.use(VueCascaderSelect);
// or
export default {
  name: 'MyComponent',
  components: {
    VueCascaderSelect,
  },
  ...
};

3. Insert the Cascader Select into your app template.

<template>
  <vue-cascader-select
    :options="options"
    :onClear="(val) => value = ''"
    :onSelect="(val) => value = val"
    :value="value"
  />
</template>

4. Define your hierarchical options for the cascading dropdown.

[
  {
    label: 'JavaScript',
    value: 'javascript',
    disabled: true,
    options: [
      { label: 'Vue', value: 'Vue' },
      { label: 'React', value: 'React' },
      { label: 'Angular', value: 'Angular' },
    ],
  },
  {
    label: 'Backend',
    value: 'Backend',
    disabled: true,
    options: [
      { label: 'Ruby on Rails', value: 'Ruby on Rails' },
      { label: 'NodeJS', value: 'NodeJS' },
      { label: 'Elixir', value: 'Elixir' },
    ],
  },
];
