1. Load the stylesheet tree-select.css in the header for the basic styling of the tree select.

2. Create a normal input field on the page.

<input type="text" name="test" id="test" placeholder="Select An Option">

3. Prepare your own hierarchical data for the multi-level dropdown list.

const myData = [{
  title: 'text1',
  value: 1,
  child: []
}, {
  title: 'text2',
  value: 2,
  child: []
},
  {
    title: 'text3',
    value: 3,
    child: [
      {
        title: 'lv2 text3',
        value: 3,
        child: []
      },
      {
        title: 'lv2 text4',
        value: 4,
        child: [
          {
            title: 'lv3 text3',
            value: 3,
            child: []
          },
          {
            title: 'lv3 text4',
            value: 4,
            child: []
          },
          {
            title: 'lv3 text5',
            value: 5,
            child: []
          },
        ]
      },
      {
        title: 'lv2 text5',
        value: 5,
        child: []
      }
    ]
