一、下拉菜单

1.基本下拉菜单

如需使用下列菜单,只需要在class .dropdown 内加上下拉菜单即可。下面的实例演示了基本的下拉菜单:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body>
<div class="dropdown">
<button type="button" class="btn dropdown-toggle"
data-toggle="dropdown">
二手家电
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li>
<a href="#">冰箱</a>
</li>
<li>
<a href="#">洗衣机</a>
</li>
<li>
<a href="#">
电视
</a>
</li>
<li class="divider"></li>
<li>
<a href="#">热水器</a>
</li>
</ul>
</div>
</body>
</html>

2.标题

您可以使用 class dropdown-header 向下拉菜单的标签区域添加标题

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body>
<div class="dropdown">
<button type="button" class="btn dropdown-toggle"
data-toggle="dropdown">
58二手市场
<span class="caret"></span>
</button>
<ul class="dropdown-menu" >
<li class="dropdown-header">二手电器(下拉菜单标题)</li>
<li>
<a href="#">冰箱</a>
</li>
<li>
<a href="#">洗衣机</a>
</li>
<li>
<a href="#">
电视
</a>
</li>
<li class="divider"></li>
<li class="dropdown-header">二手家私(下拉菜单标题)</li>
<li>
<a href="#">沙发</a>
</li>
<li>
<a href="#">电脑桌</a>
</li>
<li>
<a href="#">床</a>
</li>
</ul>
</div>
</body>
</html>

二、按钮组

按钮组允许多个按钮被堆叠在同一行上。当你想要把按钮对齐在一起时,这就显得非常有用。

下面的表格总结了 Bootstrap 提供的使用按钮组的一些重要的 class:

1.基本的按钮组

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>

2.按钮工具栏

class .btn-toolbar 的使用

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body>
<div class="btn-toolbar" role="toolbar">
<div class="btn-group">
<button type="button" class="btn btn-default">按钮 1</button>
<button type="button" class="btn btn-default">按钮 2</button>
<button type="button" class="btn btn-default">按钮 3</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-default">按钮 4</button>
<button type="button" class="btn btn-default">按钮 5</button>
<button type="button" class="btn btn-default">按钮 6</button>
</div>
<div class="btn-group">

<button type="button" class="btn btn-default">按钮 8</button>
<button type="button" class="btn btn-default">按钮 9</button>
</div>
</div>
</body>
</html>

3.嵌套

在一个 .btn-group 内嵌套另一个 .btn-group 。当您向让下拉菜单与一系列按钮组合使用时,就会用到这个。

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body> <div class="btn-group">
<button type="button" class="btn btn-default">按钮 1</button>
<button type="button" class="btn btn-default">按钮 2</button>
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle"
data-toggle="dropdown">
二手家电
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">冰箱</a></li>
<li><a href="#">洗衣机</a></li>
</ul>
</div>
</div>
</body>
</html>

4.垂直的按钮组

class .btn-group-vertical 的使用

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body> <div class="btn-group-vertical">
<button type="button" class="btn btn-default">按钮 1</button>
<button type="button" class="btn btn-default">按钮 2</button>
<div class="btn-group-vertical">
<button type="button" class="btn btn-default dropdown-toggle"
data-toggle="dropdown">
二手家电
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">冰箱</a></li>
<li><a href="#">洗衣机</a></li>
</ul>
</div>
</div>
</body>
</html>

5.分割的按钮下拉菜单

分割的按钮下拉菜单使用与下拉菜单按钮大致相同的样式,但是对下拉菜单添加了原始的功能。分割按钮的左边是原始的功能,右边是显示下拉菜单的切换。

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body> <div class="btn-group">
<button type="button" class="btn btn-default">默认</button>
<button type="button" class="btn btn-default dropdown-toggle"
data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">功能1</a></li>
<li><a href="#">功能2</a></li>
<li><a href="#">其他功能</a></li>
<li class="divider"></li>
<li><a href="#">分离的链接</a></li>
</ul>
</div>
<div class="btn-group">
<button type="button" class="btn btn-primary">原始</button>
<button type="button" class="btn btn-primary dropdown-toggle"
data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">功能1</a></li>
<li><a href="#">功能2</a></li>
<li><a href="#">其他功能</a></li>
<li class="divider"></li>
<li><a href="#">分离的链接</a></li>
</ul>
</div> </body>
</html>

6.按钮上拉菜单

菜单也可以往上拉伸的,只需要简单地向父 .btn-group 容器添加 .dropup 即可。

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://apps.bdimg.com/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head>
<body style="margin-top:200px;"> <div class="btn-group">
<button type="button" class="btn btn-default">默认</button>
<button type="button" class="btn btn-default dropdown-toggle"
data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">功能1</a></li>
<li><a href="#">功能2</a></li>
<li><a href="#">其他功能</a></li>
<li class="divider"></li>
<li><a href="#">分离的链接</a></li>
</ul>
</div>
<div class="btn-group dropup">
<button type="button" class="btn btn-primary">原始</button>
<button type="button" class="btn btn-primary dropdown-toggle"
data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
