Twitter Bootstrap下拉菜单 [英] Twitter Bootstrap dropdown menu

问题描述

我想在其顶部导航栏中使用Twitter Bootstrap的下拉菜单。你可以看到一个在这里工作的例子。 http://twitter.github.com/bootstrap/#

I'm trying to use Twitter Bootstrap's dropdown menu in its top nav bar. You can see an example working here. http://twitter.github.com/bootstrap/#

在我的，指示它是一个下拉菜单的箭头显示在菜单上，但当我悬停或点击它不显示我的下拉链接。我认为我已经包括所有必要的类，我不相信Twitter的需要javascript。

In mine, the arrow indicating that it's a dropdown shows on the menu but when I hover or click on it it doesn't reveal my dropdown links. I think I've included all the necessary classes, and I don't believe Twitter's requires javascript.

您看到我做错了吗？

我的下拉菜单

  <div class='topbar' data-dropdown="dropdown">

  <div class='fill'>
    <div class='container'>
    <ul class="nav">

      <li><%= link_to 'Home', main_app.root_path %></li>
          <li><%= link_to 'Outlines', main_app.outlines_path %></li>
       <li class="dropdown">
        <a href="#" class="dropdown-toggle">Assessment</a>
        <ul class="dropdown-menu">
        <li><a href="#">second link </a></li>
        <li><a href="#">third link </a></li>
        </ul>
      </li>

  ..... I go on to close all the divs etc. The nav bar looks great but the dropdown just doesn't work.
