Bootstrap NavBar下拉菜单
Bootstrap NavBar下拉菜单
提问于 2021-01-06 13:19:37
自从我使用Bootstrap并尝试让我的NavBar切换下拉菜单以来，这已经是一个热门的时刻了。我在这里看过所有的bootstrap文档和其他论坛。我是不是漏掉了什么？
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="index.html">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Links</a>
<div class="dropdown-menu">

确保正确插入bootsrap库，并确保nav content id等于target
