我正在使用 Bootstrap 创建一个站点，我想制作两个导航菜单。所以我编写了以下代码:
<?php require_once 'php/functions/edu_functions.php'; ?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<style type="text/css">
</style>
<!-- Bootstrap -->

因此，如果您在连接到 Bootstrap 样式的 html 文档上运行它，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，当我将鼠标悬停在菜单导航 1 的按钮上时，它可以正常工作:
但是当我将鼠标悬停在菜单导航 2 的按钮上时，它再次向我显示顶部菜单而不是主菜单项:
我不知道为什么会这样，我也尝试用默认菜单导航替换代码，但还没有用!
因此，如果您对此有任何想法，请告诉我...谢谢!
最佳答案
两个导航都有 data-target="#bs-example-navbar-collapse-1"
您需要更改其中一个菜单的 ID 和数据目标。
关于css - Bootstrap 无法识别移动设备中的两个菜单导航，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44316276/
