Jquery UI Sort Plugin For Easy Sortable Tree-Type Structure

JQuery is a sortable tree plug-in that enables the user to reorder items in a menu tree by drag and drop. Based on jQuery UI sortable functionality.

This is a sortable jquery UI helper for an easy-to-use tree-type structure.

How to make use of it:

1. Load jQuery and jQuery UI within the doc.

<link rel="stylesheet" href="/path/to/cdn/jquery-ui.css" />
<script src="/path/to/cdn/jquery-ui.min.js"></script>
<script src="/path/to/cdn/jquery.slim.min.js"></script>

2. Create a hierarchical tree from nested HTML lists as follows:

<ul id="tree">
  <li class="tree-branch branch-level-1">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 1</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-2">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 2</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-2">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 3</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-3">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 4</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-3">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 5</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-2">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 6</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
  <li class="tree-branch branch-level-1">
    <div class="contents">
      <div class="branch-drag-handler">
        <span class="branch-title">Branch 7</span>
      </div>
    </div>
    <div class="children-bus"></div>
  </li>
</ul>
