本文实例讲述了Bootstrap组件之下拉菜单,多级菜单及按钮布局方法。分享给大家供大家参考，具体如下：

下拉菜单

菜单： ,dropdown（.dropup改变这个是上显示）   data-toggle="dropdown" (激活文本处)      .dropdown-menu   .pull-left   .pull-right
按钮组：.btn-group(各种类为btn的标签集合)    .btn-toolbar（按钮导航条） .btn-group-vertical   .btn-mini .btn-small   .btn-large   .nav-pills（胶囊样式）
导航： .nav   .nav-tabs .pull-right   .disabled     .nav-stacked（堆叠） .nav-list     data-toggle="tab"    .tabbable(容器)   .tabs-left (right , below)   .tab-content

注意： .dropdown-submenu(多级导航中，可能bootstrap中没有)自行添加：

<style type="text/css">  .dropdown-submenu {   position: relative;  }  .dropdown-submenu > .dropdown-menu {   top: 0;   left: 100%;   margin-top: -6px;   margin-left: -1px;   -webkit-border-radius: 0 6px 6px 6px;   -moz-border-radius: 0 6px 6px;   border-radius: 0 6px 6px 6px;  }  .dropdown-submenu:hover > .dropdown-menu {   display: block;  }  .dropdown-submenu > a:after {   display: block;   content: " ";   float: right;   width: 0;   height: 0;   border-color: transparent;   border-style: solid;   border-width: 5px 0 5px 5px;   border-left-color: #ccc;   margin-top: 5px;   margin-right: -10px;  }  .dropdown-submenu:hover > a:after {   border-left-color: #fff;  }  .dropdown-submenu.pull-left {   float: none;  }  .dropdown-submenu.pull-left > .dropdown-menu {   left: -100%;   margin-left: 10px;   -webkit-border-radius: 6px 0 6px 6px;   -moz-border-radius: 6px 0 6px 6px;   border-radius: 6px 0 6px 6px;  }</style>

添加这段css即可使.dropdown-submenu有效

实现菜单样式：

<!doctype html><html><head><meta charset="utf-8"><title>无标题文档</title><script type="text/javascript" src="bootstrap-3.3.6/js/jquery.cyan1.js"></script><script type="text/javascript" src="bootstrap-3.3.6/js/dropdown.js"></script><link rel="stylesheet" href="bootstrap-3.3.6/dist/css/bootstrap.min.css" rel="external nofollow" /> <style type="text/css">  .dropdown-submenu {   position: relative;  }  .dropdown-submenu > .dropdown-menu {   top: 0;   left: 100%;   margin-top: -6px;   margin-left: -1px;   -webkit-border-radius: 0 6px 6px 6px;   -moz-border-radius: 0 6px 6px;   border-radius: 0 6px 6px 6px;  }  .dropdown-submenu:hover > .dropdown-menu {   display: block;  }  .dropdown-submenu > a:after {   display: block;   content: " ";   float: right;   width: 0;   height: 0;   border-color: transparent;   border-style: solid;   border-width: 5px 0 5px 5px;   border-left-color: #ccc;   margin-top: 5px;   margin-right: -10px;  }  .dropdown-submenu:hover > a:after {   border-left-color: #fff;  }  .dropdown-submenu.pull-left {   float: none;  }  .dropdown-submenu.pull-left > .dropdown-menu {   left: -100%;   margin-left: 10px;   -webkit-border-radius: 6px 0 6px 6px;   -moz-border-radius: 6px 0 6px 6px;   border-radius: 6px 0 6px 6px;  } </style></head><body><ul class="nav nav-pills"><li class="dropdown"> <a href="#" rel="external nofollow" rel="external nofollow"
