javascript - 带有导航栏固定顶部的双 Bootstrap 菜单

Question

找到了很多例子，但似乎没有一个是我正在寻找的，而且似乎无法让它按照我需要的方式工作。

This is the closest example I can find ，虽然 bootply 看起来不一样。

问题是当第一个菜单展开时第二个菜单被隐藏(在移动模式下)

我需要 2 个菜单，都位于顶部。我可以让它与 >= small 一起工作，但是带有折叠菜单的 xs 让我很难受。基本上寻找标准修复导航两次。我不想在第一个菜单展开时隐藏第二个菜单。需要它看起来/行为完全相同。

不好意思，我是后端，前端有限。

如果没有直接的答案，我是否必须设置 Nav 标签？还是应该将第二个菜单放在 div 或其他东西中？我原以为从 bootstrap 复制示例两次会起作用，但显然不行。如果我能从隐藏中获取二级菜单，我想我可以解决剩下的问题。
