title: avoid treeview collapse on click of treeview text in jquery
body: <p>I need to avoid the collapse of jquery treeview on click of treeview links/text.</p>
  
  <p>For example, if i am showing a list of <code>directories/subdirectories</code> in treeview, I need to collapse the treeview only while clicking the <code>+/- image</code> and not on clicking the <code>directories</code></p>
