Setting nodeContent when using ul as datasource

[Mohammad Reza Saberi]

I have the following ul structure that shows well on the page. It's just I do not know how to display the node contents. Following is what I have tried.

<ul id="ul-data">
  <li title="Project Manager">Reza Saberi
    <ul>
       <li title="Project Associate">Ali Karimi</li>
       <li title="Data Analyst">Ahmad Basir</li>
    </ul>
  </li>
</ul>

and the following is the js:

$('#chart').orgchart({
  'data' : $('#ul-data'),
  'pan': true,
  'nodeContent': 'title'
});
