摘要：Bootstrap组件之下拉菜单,多级菜单及按钮布局方法实例
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： [b]下拉菜单[/b] [b]菜单：[/b] ,dropdown（.dropup改变这个是上显示）   data-toggle="dropdown" (激活文本处)      .dropdown-menu   .pull-left   .pull-right [b]按钮组：.[/b]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） [b]导航：[/b]  .nav   .nav-tabs  .pull-right   .disabled     .nav-stacked（堆叠）  .nav-list     data-toggle="tab"    .tabbable(容器)   .tabs-left (right  , below)   .tab-content [b]注意：[/b] .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 [b]实现菜单样式：[/b]
