Question

Bootstrap 3 Dropdown Menu

Yah*_*oto 1 html5 css3 twitter-bootstrap

Despite the many, many tutorials I have searched through, the dropdown feature of my navigation bar is not functioning. Please help if you know some sort of difference with multidimensional dropdown menus in Bootstrap 3 that I am not seeing.

您的文件有很多内容:

你的doctype错了.当你应该只使用HTML5声明时,你正在指定XHTML 1.0.
正如@sbat上面指出的那样,你错过了Bootstrap脚本文件.

根据通常的教程,我已经完全按照下面的格式设置了你的模板.如果您有任何疑问或需要其他任何问题,请与我们联系.
