如何使用树助手在cakephp 2中创建动态菜单？

我正在使用CakePHP2树助手和引导js/css创建动态菜单

我想要以下输出：

<ul class="nav navbar-nav">
          <li class="active"><a href="#"> Home </a></li>

      <li class="dropdown">
          <a data-toggle="dropdown" class="dropdown-toggle" href="#">About Us <span class="caret"></span></a>
          <ul class="dropdown-menu md-menu">
           <li><a href="#">Styles </a></li>
          </ul>
        </li>

      </ul>

我还检查了此url，但未成功：

基本上，我想将类添加到内部ul标记中

谢谢
