title: Expand jsTree node when parent is clicked
body: <p>I am trying to implement a very simple tree using jsTree. I have found the documentation dense and overwhelming.</p>
  
  <p>Right now, I expand / collapse a node by clicking the arrow shown here:</p>

  <p>I want to be able to expand / collapse by clicking the node name too:</p>

  <p>The code I am using is simple; I have not altered the javascript for jsTree:</p>
  
  <pre><code>&lt;ul id="tree"&gt;
     &lt;li&gt;
        SubFolder1
        &lt;ul id="tree"&gt;
           &lt;li data-jstree='{"icon":"/Images/blue-folder.png"}'&gt;Pub 1&lt;/li&gt;
        &lt;/ul&gt;
     &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
