问题描述

好的，所以我在做一些非常简单的事情时遇到了一个奇怪的问题，在经过两天的高低搜索之后，我想知道这里是否有人可以向我指出正确的方向:

Ok, so I've run into a weird problem while doing something pretty straightforward, and after two days of searching high and low, I wonder if anybody here can point me in the right direction:

我正在使用Twitter Bootstrap用Nav-Pills构建一个简单的下拉菜单.我正在遵循所有说明(没什么复杂的)，并通过CDN链接到bootstrap.min.js，bootstrap.min.css和jquery.min.js.

I'm building a simple dropdown menu with Nav-Pills using Twitter Bootstrap.I'm following all the instructions (nothing complicated), and am linking to bootstrap.min.js, bootstrap.min.css and jquery.min.js via cdn.

但是，输出显示下拉菜单项两次，一次是垂直堆叠的翻转下拉列表，非常好，弹出并隐藏，但是覆盖的是另一组完全相同的drowdownlist项，这一次水平展开，并一直在那里显示，一直显示，没有添加任何切换功能.

However, the output shows the dropdown items twice, once as a toggled dropdownlist that is stacked vertically really nice and pops up and hides as you would expect, but then also overlayed is another set of the exact same drowdownlist items, this time horizontally spread out, and just there, displaying all the time, with no toggle functionality added.

顺便说一句，我试图将其重新创建为jsfiddle，在那儿，甚至没有显示下拉列表.

BTW, i tried to recreate this as a jsfiddle and over there, the dropdown list just doesn't even show.

这对我来说很奇怪，我有点超出方向了.有什么想法吗?非常感谢您的帮助！

This is so weird to me, i've kind of run out of directions. Any ideas, anyone? Help is much appreciated!

我的代码:

    <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" href="main.css">

   <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
</head>
<body>
<nav id="navbar-bottom">
        <div class="container-fluid">
            <ul class="nav nav-pills pull-right">
                <li class="active"><a href="#">Active Link</a></li>
                <li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button">Dropdown Link</a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Option1</a></li>
                        <li><a href="#">Option2</a></li>
                    </ul>
                </li>
            </ul>
        </div>
</nav>
