Question

在Bootstrap中遇到垂直导航栏的问题。

在此处查看代码笔：link

注意＆＃34;如何运作＆＃34;部分显示传统的下拉？我希望它能够与导航顺利内联，而不会弹出一个覆盖其他项目的下拉列表。我已经为这个小时摆弄了这件事。我确定它与位置，显示或默认引导属性有关。

为了澄清，我正在寻找a UI like this子菜单。了解＆＃34;如何工作＆＃34;部分按下它下面的菜单项？

有任何指示吗？

HTML

  <ul class="nav items">
       <li class="dropdown">
         <a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="true">Works <span class="caret"></span></a>
         <ul class="dropdown-menu" role="menu">
           <li>
             <a href="#">DASHBOARD</a>
             </li>
             <li>
             <a href="#">DASHBOARD</a>
             </li>

       </li>
      <li><span></span>Dashboards </li>
