Question

我有一个bootstrap导航栏。我有多个下拉项目。

现在我有了另一个div col-md-3。

在这个div中，我想显示我悬停的下拉项目。现在，如果我将鼠标悬停在下拉菜单上，则显示子菜单而不是单击。

那么如何在该div中显示drodown菜单的子项呢？

我希望子项目在下拉列表中，并且也在那个侧栏中。

我的代码是这样的：

  <nav class="navbar navbar-default">
   <div class="container-fluid">
      <!-- Brand and toggle get grouped for better mobile display -->
      <div class="navbar-header">
         <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
         <span class="sr-only">Toggle navigation</span>
         <span class="icon-bar"></span>
         <span class="icon-bar"></span>
         <span class="icon-bar"></span>
         </button>
      </div>
      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
         <ul class="nav navbar-nav">
            <li><a  href="#">Dashboard</a></li>
            <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Administration <span class="caret"></span></a>
                <ul class="dropdown-menu">

您的代码是正确的，但似乎您忘记在代码中包含jQuery。我使用你的代码创建了一个Codepen，并且在包含Bootstrap库之前我已经在底部包含了jQuery.js。正如您所看到的，下拉项目工作正常，当您从代码中删除jQuery脚本时，您可以重现已损坏的场景。

以下是链接：Codepen Link

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

根据bootstrap下拉项目更改`div`的内容
