Question

我尝试使用bootstrap做一个小的下拉菜单，但没有成功。这是代码：

<ul class="nav navbar-nav">
                <li>
                    <a href="#">Text</a>
                </li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a href="logout.php">Logout</a></li>
                    </ul>
                </li>
</ul>

知道它为什么不起作用？感谢。

下拉菜单不适用于引导程序
