下拉菜单无法在标题中使用

I have a very simple bootstrap header. The only issue with it is that the dropdown menu in the header does not drop down... I will post my code below

我有一个非常简单的bootstrap头。唯一的问题是标题中的下拉菜单没有下拉...我将在下面发布我的代码

        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
                <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="#">My Project</a>
        </div>
        <div id="navbar" class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li class="active"><a href="#">Home</a></li>
                <li><a href="#">Contact</a></li>
                <li runat="server" class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown<b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Menu Item 1</a></li>
                        <li><a href="#">Menu Item 2</a></li>
                        <li><a href="#">Menu Item 3</a></li>
                        <li><a href="#">Menu Item 4</a></li>
                    </ul>
                </li>
            </ul>              
        </div>
        <!--/.nav-collapse -->
    </div>
</nav>

I know this is a lot of code to post, just wanted to make sure nothing was left out.

我知道这是要发布的很多代码,只是想确保没有遗漏任何内容。

You need to link the JQuery for dropdown menu to work. Add it before bootstrap.min.js.

您需要链接JQuery for下拉菜单才能工作。在bootstrap.min.js之前添加它。

After adding JQuery it goes like this.

添加JQuery后就像这样。

<!-- Font awesome reference -->
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" />

<!-----add this JQuery before bootstrap.min.js----->

Hope this help.!
