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> <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> <button type="button" class="btn btn-default">按钮 3</button> </div> </body> </html>
效果:
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 7</button> <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>
效果:
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>
效果:
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>
效果:
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>
效果:
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"> <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>
