 </div> 
 <!--创建一个可折叠的导航面板--> 
 <div data-role="content"> 
 <div data-role="collapsible" data-theme="e"> 
 <h4>文学历史</h4> 
 <ul data-role="listview"> 
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >明代</a></li>

 </ul> 
 </div> 
 <!--显示人文社科的可折叠面板--> 
 <div data-role="collapsible" data-theme="b" data-collapsed="false"> 
 <h4>人文社科</h4> 
 <ul data-role="listview">

  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >移动开发</a></li> 
 </ul> 
 </div> 
 </div> 
 <div data-role="footer" data-position="fixed"> 
 <h1>请单击“+”按钮进行展开</h1> 
 </div> 
</div> 
</body> 
</html>

代码分析：

        通过data-role=" collapsible "创建可折叠的div，再在其中通过 data-role=" listview "创建列表框
        data-theme : 指定预定义样式（也可以使用样式构建器创建自定义样式）
        data-collapsed="false" : 表示默认不折叠

效果图：
