Twitter引导程序导航丸与下拉列表

Question

我使用Twitter bootstrap创建了nav-pills 3.
除了下拉菜单外,一切都很好.
文档显示选项卡链接的布局,但不显示内容:http://getbootstrap.com/components/#nav-dropdowns

我想在用户选择其中一个下拉链接时显示内容.

<div class="tabbable">
    <ul class="nav nav-tabs nav-pills" id="myTab">
        <li class="active"> <a href="#tab1" data-toggle="tab">Part 1</a>

        </li>
        <li class=""> <a href="#tab2" data-toggle="tab">Part 2</a>

        </li>
        <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Activity <span class="caret"></span></a>

            <ul class="dropdown-menu" role="menu">
                <li><a href="#tab3">Action</a>
                </li>
                <li><a href="#tab4">Another action</a>
                </li>
            </ul>
        </li>
    </ul>
    <br>
    <div class="tab-content">
        <div class="tab-pane active" id="tab1">aaaaaaaaaaaa</div>
        <div class="tab-pane" id="tab2">bbbbbbbbbbbb</div>
        <div class="tab-pane" id="tab3">cccccccccccccc</div>
