Dropup Bootstrap当固定在底部时切换菜单

Question

我有一个底部固定的菜单，并希望切换到dropup而不是down。我已经尝试了所有在stackoverflow中找到的解决方案（就像这个How to get a Bootstrap dropdown submenu to 'dropup'），用.dropup类包装，或者将它添加到元素等等，但没有任何工作。这是我的代码：

EDIT 2 - 点出错误： 一次是在对方的回答中指出。另外，我通过自定义css类给它height: 50px;，这使得菜单停止了dropup。

 <nav class="navbar navbar-default navbar-fixed-bottom"> 
     <div class="container"> 
      <div class="navbar-header"> 
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
       <span class="sr-only">Toggle navigation</span> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
      </button> 
      <a class="navbar-brand" href="#">Linares de Mora</a> 
      </div> 
      <div id="navbar" class="collapse navbar-collapse"> 
      <ul class="nav navbar-nav navbar-right"> 
       <li><a href="#about">Que Hacer</a></li> 
       <li><a href="#contact">Alojamiento</a></li> 
       <li><a href="#contact">Historia</a></li> 
       <li><a href="#contact">Comida</a></li> 
       <li class="dropdown"> 
       <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Más <span class="caret"></span></a> 

        <ul class="dropdown-menu"> 
        <li><a href="#">Action</a></li> 
        <li><a href="#">Another action</a></li> 
        <li><a href="#">Something else here</a></li> 
        <li role="separator" class="divider"></li>

       </li> 
      </ul> 
      </div><!--/.nav-collapse -->

检查此链接https://jsfiddle.net/edz80vw5/

<nav class="navbar navbar-default navbar-fixed-bottom"> 
    <div class="container"> 
     <div class="navbar-header"> 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
      <span class="sr-only">Toggle navigation</span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
     </button> 
     <a class="navbar-brand" href="#">Linares de Mora</a> 
     </div> 
     <div id="navbar" class="collapse navbar-collapse"> 
     <ul class="nav navbar-nav navbar-right"> 
      <li><a href="#about">Que Hacer</a></li> 
      <li><a href="#contact">Alojamiento</a></li> 
      <li><a href="#contact">Historia</a></li> 
      <li><a href="#contact">Comida</a></li> 
      <li class="dropup"> 
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Más <span class="caret"></span></a> 

       <ul class="dropdown-menu"> 
       <li><a href="#">Action</a></li> 
       <li><a href="#">Another action</a></li> 
       <li><a href="#">Something else here</a></li> 
       <li role="separator" class="divider"></li> 
       <li class="dropdown-header">Nav header</li> 
       <li><a href="#">Separated link</a></li> 
       <li><a href="#">One more separated link</a></li> 
       </ul> 

      </li> 
     </ul> 
     </div><!--/.nav-collapse --> 
    </div> 
    </nav> 

的差异是由第一UL最后李元素与类dropup，而不是下拉制造。
