I work with jQuery Mobile and according to the documentation the navigation bar will be wrapped in five elements. However, in my work with him, he wraps only 4 elements. Is this the expected behavior?

Code
<div data-role="page" id="images"> <div data-role="header"> <h1><%= @disease.name %></h1> <a href="index.html" data-icon="plus" class="ui-btn-right">Add</a> </div> <div data-role="content"> <p>Images will be here.</p> </div> <div data-role="footer"> <div data-role="navbar"> <ul> <li><a href="#images" class="ui-btn-active">Images</a></li> <li><a href="#symptoms">Symptoms</a></li> <li><a href="#treatments">Treatments</a></li> <li><a href="#notes">Notes</a></li> </ul> </div> </div> </div>
