用Bootstrap创建的热门导航不会折叠子菜单

我已经创建了一个Navbar Header的顶部导航，其中有一个带有下拉子菜单和插入符号的4个主要链接。用Bootstrap创建的热门导航不会折叠子菜单

下拉子菜单没有折叠。我试图找到问题，但找不到它。请参阅下面的代码片段。

的data-toggle="drop-down"应该data-toggle="dropdown"，这一切现在工作正常。

看看并让我知道您的反馈。谢谢！

改变这一点：

<a href="#" class="dropdown-toggle" data-toggle="drop-down">Products <b class="caret"></b></a>

此：

<a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Products <b class="caret"></b></a>
