<link rel="stylesheet" href="assets/vendor/libs/jstree/jstree.css" />

Include the following vendors script in the "Vendors JS" area from the page's footer:

<script src="assets/vendor/libs/jstree/jstree.js"/>

<div id="jstree-basic">
  <ul>
    <li data-jstree='{"icon" : "ri-folder-3-line"}'>
      css
      <ul>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>

        </li>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>
          style.css
        </li>
      </ul>
    </li>
    <li class="jstree-open" data-jstree='{"icon" : "ri-folder-3-line"}'>
      img
      <ul data-jstree='{"icon" : "ri-folder-3-line"}'>

          bg.jpg
        </li>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>
          logo.png
        </li>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>
          avatar.png
        </li>
      </ul>
    </li>
    <li class="jstree-open" data-jstree='{"icon" : "ri-folder-3-line"}'>
      js
      <ul>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>jquery.js</li>
        <li data-jstree='{"icon" : "ri-folder-3-line"}'>app.js</li>
      </ul>
    </li>
    <li data-jstree='{"icon" : "ri-file-text-line"}'>
      index.html
    </li>
    <li data-jstree='{"icon" : "ri-file-text-line"}'>
      page-one.html
    </li>
    <li data-jstree='{"icon" : "ri-file-text-line"}'>
      page-two.html
    </li>
  </ul>
</div>

$("#jstree-basic").jstree()

Custom Icons

You can customize icons by passing icon parameter.
You can also create a treeview with JS without writing HTML.

 <div id="jstree-custom-icons"></div>

$("#jstree-custom-icons").jstree({
  core: {
    data: [
      {
        text: 'css',
        children: [
          { text: 'app.css', type: 'css' },
          { text: 'style.css', type: 'css' }
        ]
      },
      {
        text: 'img',
        state: { opened: true },
        children: [
          { text: 'bg.jpg', type: 'img' },
          { text: 'logo.png', type: 'img' },
          { text: 'avatar.png', type: 'img' }
        ]
      },
      {
        text: 'js',
        state: { opened: true },
        children: [
          { text: 'jquery.js', type: 'js' },
          { text: 'app.js', type: 'js' }
        ]
      },
      { text: 'index.html', type: 'html' },
      { text: 'page-one.html', type: 'html' },
      { text: 'page-two.html', type: 'html' }
    ]
  },
  plugins: ['types'],
  types: {
    default: { icon: 'ri-folder-3-line' },
    html: { icon: 'ri-html5-fill text-danger' },
    css: { icon: 'ri-css3-fill text-info' },
    img: { icon: 'ri-image-fill text-success' },
    js: { icon: 'ri-javascript-line text-warning' }
  }
})

          { text: 'app.css', type: 'css' },
          { text: 'style.css', type: 'css' }
        ]
      },
      {
        text: 'img',
        state: { opened: true },
        children: [
          { text: 'bg.jpg', type: 'img' },
          { text: 'logo.png', type: 'img' },
          { text: 'avatar.png', type: 'img' }
        ]
      },
      {
        text: 'js',
        state: { opened: true },
        children: [
          { text: 'jquery.js', type: 'js' },
          { text: 'app.js', type: 'js' }
