Question

我有一个带有bootstrap的基本.net网站（基本上只是用vs-2015，web-form启动了一个新项目）。

由于某些未知原因，当我将Bootstrap 3调整大小工具设置为col-md时，导航栏折叠功能无法正常工作（请参阅下面的内容）：

每个其他尺寸都能正常工作。当我有很多<li>

时，问题只发生在col-md上

这是我的母版页代码（HTML）

    </form>
</body>
</html>

是否有人知道如何解决此问题？

Answer 1

来自@vanburen的解释正确无误。根据我原先相信的可用（全宽 - 用于）显示宽度，引导崩溃不会触发。它在宽度“sm”上触发，因此解决问题的唯一方法是覆盖引导程序。

再次感谢@vanburen，我希望你把它放在答案中，这样我就可以投票给你......
