jquery-mobile – 如何在jQuery mobile 1.4.0中制作下拉面板？

我在我的jQuery移动应用程序中有以下面板,我想让它下拉,如下图所示,而不是从页面边缘滑动.这可以在jQuery mobile中完成吗？我该怎么做？

<div data-role="page"    id="MainPage"  >

  <div data-role="panel" id="Mainnavpanel" data-theme="b" data-display="overlay" data-      position="right" data-position-fixed="true">

   <ul data-role="listview"><li>
   <a href="#MainPageheader" data-rel="close" class="ui-btn" >Close</a></li>
   <li><a href="Page1.html" class="ui-btn"  data-transition="none">Page1</a></li>
  <li><a href="Page2.html" class="ui-btn"  data-transition="none">Page2</a></li>
  <li><a href="Page3.html" class="ui-btn"  data-transition="none">Page3</a></li>
  </ul>
  </div>

   <div  data-role="header"   id="MainPageheader"  data-position="fixed"  data-tap-     toggle="false" data-fullscreen="false">

    <a href="#Mainnavpanel" data-role="button"  class="ui-btn ui-btn-icon-left ui-btn- icon-notext ui-nodisc-icon ui-icon-bars"></a>
    <div> <font size="6px"> Main Page </font></div>

    </div> 
    <div data-role="content" >

    //content
    </div>
    </div>

<div data-role="popup" id="popupID" data-arrow="t">
  <!-- content -->
</div>

<a href="#popupID" data-rel="popup">Menu</a>
