你必須在子菜單下拉菜單中一個錯字。它指定爲「ui」而不是「ul」。

更改您的子菜單下拉菜單來

<ul class="dropdown-menu"> 
    <li><a tabindex="-1" href="#">Submenu 1</a></li> 
    <li><a tabindex="-1" href="#">Submenu 2 </a></li> 
    <li><a tabindex="-1" href="#">Submenu 3 </a></li> 
</ul>

     <a tabindex="-1" href="#">More options</a> 
     <ul class="dropdown-menu"> 
      <li><a tabindex="-1" href="#">Submenu 1</a></li> 
      <li><a tabindex="-1" href="#">Submenu 2 </a></li>

     </ul> 
     </li> 
    </ul> 
    </div>

您使用的用戶界面，而不是UL，上面的代碼是工作版本，下面是變化的。

 <ul class="dropdown-menu"> 
      <li><a tabindex="-1" href="#">Submenu 1</a></li> 
      <li><a tabindex="-1" href="#">Submenu 2 </a></li> 
      <li><a tabindex="-1" href="#">Submenu 3 </a></li> 
     </ul>
