这是一个Bootstrap4多级导航菜单插件。该插件扩展了原生bootstrap4导航栏以生成多级导航菜单并添加了很酷的CSS3动画。

使用方法

在页面中引入jquery.min.js、bootstrap4相关文件，以及bootnavbar.css、bootnavbar.js和animate.css文件。

<link rel="stylesheet" href="css/bootstrap.min.css"/>
<link rel="stylesheet" href="css/bootnavbar.css"/>
<link rel="stylesheet" href="css/animate.css"/>
<script  src="js/jquery.min.js"></script>
<script  src="js/bootstrap.min.js"></script>
<script  src="js/bootnavbar.js"></script>

HTML

<nav class="navbar navbar-expand-lg navbar-light bg-light" id="main_navbar">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">

</button>

<div class="collapse navbar-collapse" id="navbarSupportedContent">
