我正在Bootstrap中制作一个站点，我想进行两个导航菜单。.所以我对此进行了编码：
<?php require_once 'php/functions/edu_functions.php'; ?>

因此，如果您在连接到Bootstrap样式的HTML文档上运行此操作，您会注意到一切正常，除非您最小化屏幕以查看菜单导航在移动设备中的工作方式...
我的意思是，当我悬停在菜单导航的按钮上时，它可以正常工作：
1
但是，当我悬停在菜单导航2的按钮上时，它再次向我显示了顶部菜单，而不是主菜单项目：
2
我不知道为什么会发生这种事情，我也尝试用默认菜单导航替换代码，但还没有用！
所以，如果您对此有任何想法，请让我知道... thx！
两个NAV都有data-target="#bs-example-navbar-collapse-1"
您需要在其中一个菜单上更改ID和数据目标。
