Bootstrap -- 下拉菜单、输入框组、导航菜单
1. 下拉菜单
可以使用带有各种大小按钮的下拉菜单：.btn-lg、.btn-sm 或 .btn-xs。
实现下拉菜单：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

<link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>

<body>
<div class="dropdown">
<button type="button" class="btn dropdown-toggle" id="dropdownMenu" data-toggle="dropdown">

</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
