title: Extjs - Toolbar button menu dropdown with submenus. It's possible?
body: <p>I've already done a toolbar with buttons that have a dropdown menu but I need more submenu levels. It's possible to do that? Example:</p>
  
  <ul>
  <li><p>toolbarbutton -></p>
  
  <ul>
  <li>menu 1 lv 1</li>
  <li>menu 2 lv 1</li>
  <li>menu 3 lv 1->
  <ul>
  <li>submenu 1 lv 2</li>
  <li>submenu 2 lv 2</li>
  </ul></li>
  <li>menu 4 lv 1 </li>
  </ul></li>
  </ul>
  
  <p>and so on...</p>
