}

我想創建的一個下拉註銷菜單但失敗。下拉菜單不起作用。

呈現的HTML看起來也很奇怪。我無法弄清楚哪裏出了問題。請幫忙。

<ul class="navigation"> 
    <div class="navbar navbar-fixed-top"> 
     <div class="navbar-inner"> 
      <ul> 
       <li class="current first">   
        <a href="/intra/web/app_dev.php/">Home</a>   
       </li> 

       <li dropdown="dropdown">  
       <span>Leave</span>    
       <ul class="menu_level_1"> 
       <li class="first last">   
        <a href="/intra/web/app_dev.php/leave">Edit profile</a>   
       </li> 
       </ul> 
       </li> 
        <li dropdown="dropdown" class="last">   
        <span>Claim</span>   
       </li> 
      </ul> 
     </div> 
    </div> 
    <div class="content" style="margin-top: 50px;"> 
    </div> 
</ul>

檢查是否包含所有sytelsheets和js文件。我敢打賭，你錯過了knpmenu包的一些東西 – Joshua

knpmenu有它自己的CSS和JS？我認爲這是使用Jquery和Bootstrap？ –
