Q:

Insert a listView into another listView with JqueryMobile

I would like to put a listView into another listView. Is it possible? I tried this code but it doesn't work : 
<ul data-role="listview">
    <li>
          <img src="assets/img/reception.png" alt="reception" class="ui-li-icon" />
          <a href="webmail/inbox">Boîte de r&eacute;ception</a>
    </li>
    <li class="dossiers" data-role="collapsible" style="padding:0; border-width:0;">
          <h3 style="margin:0;">Dossiers</h3>
          <ul data-role="listview" data-inset="true" data-theme="d">
               <li><a href="index.html">Dossier 1</a></li>
               <li><a href="index.html">Dossier 2</a></li>
               <li><a href="index.html">Dossier 3</a></li>
           </ul>
     </li>
</ul>

With this snippet, my button "Dossiers" disappears. Then if I comment the part<ul> in the <li>, the button re-appears.
Any idea ?
Thanks !!
Ps: Sorry for my bad English, I'm French.

A:

Looks like a JQM bug to me. 
Try without data-role="collapsible" and if it helps - put a div inside the li and give it the role. 
Also try wrapping the inner listview in a div.
[edit]
JQM alpha3 was released today. See if it fixes your problem.
