      <li>Item Four</li>
      <li>Item Five</li>
    </ul>
  </li>
</ul>

In this example, we use Font Awesome for the folder icons.

<link rel="stylesheet" href="font-awesome.min.css">

Place the jslists’ JavaScript at the bottom of the web page.

<script src="jsLists.min.js"></script>

Initialize the tree list.

JSLists.applyToList('simple_list', 'ALL');
