我有这段代码片段从Bootstrap网站中提取。一切正常，除非我点击See Product，它不会显示任何内容。Bootstrap下拉菜单不起作用（不显示下拉列表）

你不必jquery.min.js和bootstrap.min.js或连接在你的HTML文件bootstrap.js。看看basic template

关闭标签之前</body>你需要添加如下因素代码

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> 
<script src="js/bootstrap.min.js"></script>

确保bootstrap.min.js文件是JS文件夹中的项目
