      <h1>Sortable List</h1>

      <p>This demo shows how to integrate the excellent <a href="https://rubaxa.github.io/Sortable/">SortableJS</a> library with Intercooler.  </p>

      <p>Note that the "server side" implementation is mocked out using mockjax, so you can see the entire
        implementation. Click the "Source Code" tab to see the code.</p>

      <h2>Explanation</h2>

      <ul>
        <li>
          Listen for the "sorted" event fired by Sortable and send the reordered list up to the server via AJAX
        </li>
      </ul>

      <h2>Demo</h2>

      <div>
        <ul class="demo-nav nav nav-pills">
          <li role="presentation" class="active"><a href="#demo" aria-controls="demo" role="tab" data-toggle="tab">Live
            Demo</a></li>
          <li role="presentation"><a href="#code" aria-controls="demo" role="tab" data-toggle="tab">Source Code</a></li>
        </ul>
      </div>

      <div class="tab-content">
        <div role="tabpanel" class="tab-pane active" id="demo">
