找到了一些例子，但似乎没有一个我正在寻找的东西，似乎无法让它以我需要的方式工作。
This is the closest example I can find，虽然bootply似乎不一样。
问题是当第一个菜单展开时（在移动模式下）第二个菜单被隐藏
我需要2个菜单，两个都粘在上面。我可以使用＆gt; = small来使用它，但是使用折叠菜单的xs会让我感到害怕。基本上寻找标准修复导航两次。第一个展开时我不想隐藏第二个菜单。需要它以完全相同的方式看/行动。
对不起，我是前端有限的后端人员。
如果没有直接答案，我是否应该设置导航标签？或者第二个菜单应该是div还是其他？我原本以为从bootstrap复制两次示例会起作用，但显然不行。如果我可以隐藏二级菜单，我想我可以解决其余的问题。
