将下拉菜单添加到 bootstrap 3 导航栏

Question

我正在使用 bootstrap3 和 django。我想更新我的导航栏以在右侧的导航栏中添加链接的下拉列表。我的引导代码：

<!-- Navigation -->
<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                <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="/">Bob and Company</a>
        </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 navbar-right">

<li class="nav-item dropdown">
    <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Current Properties</a>
    <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
      <a class="dropdown-item" href="#">Village, Texas</a>
      <a class="dropdown-item" href="#">Lake, Washington</a>
   </div>
                </li>


            </ul>
        </div>
        <!-- /.navbar-collapse -->
    </div>
    <!-- /.container -->
</nav>

到目前为止，我正在获取屏幕截图。我该如何解决这个问题才能使其正常工作？

编辑：

谢谢，好多了。链接可以垂直而不是水平。请看截图：

如果你这样做like this，它是否有效？

<li class="nav-item dropdown">
  <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
  <div class="dropdown-menu" aria-labelledby="navbarDropdown">
    <a class="dropdown-item" href="#">1</a>
    <a class="dropdown-item" href="#">2</a>
    <a class="dropdown-item" href="#">3</a>
  </div>
</li>
