我在nav-collapse中有一个下拉菜单.
当我减小窗口的宽度(例如：700px)时,导航栏正确地折叠,然后我点击btn-navbar来解除它的折叠,然后我点击下拉列表,但它不会下拉,菜单不显示.如果然后我崩溃,再崩溃,下拉开始工作.
当窗口的宽度从一开始就很小时也会发生这种情况.
就像折叠部分的高度一开始就固定在一起,它不会让下拉菜单做到这一点.

解决方法
很多人都将这报告作为回购的错误(例如
Issue #5671,Issue #5890,Issue #6019).
针对#5671,有人指出as per the docs on responsive Navbar,当使用类navbar-collapse时,您还必须包括崩溃.看来你的例子似乎也是这样(尽管容易被忽视)的缺陷.
