Question

我有以下呈现的下拉列表（来自我的rails应用程序）：

<nav class="navbar navbar-inverse navbar-fixed-top topbar" role="navigation">
  <div class="container-fluid">
    <div class="navbar-header">
      <button class="navbar-toggle" data-target=".navbar-collapse" data-toggle="collapse" type="button">
        <span class="sr-only">Toggle navigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>
      </button>
      <a href="/"></a></div>
    <div class="collapse navbar-collapse navbar-right">
      <ul class="nav navbar-nav">
        <li><a href="/users/edit">Edit account</a></li>
        <li><a data-method="delete" href="/users/sign_out" rel="nofollow">Sign out</a></li>
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" href="#">Admin<span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="/users">Users</a></li>
            <li><a href="#"> Another action</a></li>
            <li class="divider"></li>
            <li><a href="#"> Another action2</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

显示如下：

partial_menu

它看起来不错，但是下拉列表不起作用。我让它工作了一段时间，但我无法弄清楚为什么这不起作用（下拉列表只是一个链接到＃＆＃39 ;;即它赢了＆＃39; t下拉）。

日志文件什么都没有。我不知道在哪里解决这个问题。我该如何解决这个问题？

编辑：从头标记添加js 这些包括：

Answer 1

您必须通过JavaScript调用下拉列表：

 <script>
        $('.dropdown-toggle').dropdown();
    </script>

在脚本中添加此代码
