本文實例講述了Bootstrap組件之下拉菜單,多級菜單及按鈕布局方法。分享給大家供大家參考，具體如下：

下拉菜單

菜單： ,dropdown（.dropup改變這個是上顯示）   data-toggle="dropdown" (激活文本處)      .dropdown-menu   .pull-left   .pull-right
按鈕組：.btn-group(各種類為btn的標簽集合)    .btn-toolbar（按鈕導航條） .btn-group-vertical   .btn-mini .btn-small   .btn-large   .nav-pills（膠囊樣式）
導航： .nav   .nav-tabs .pull-right   .disabled     .nav-stacked（堆疊） .nav-list     data-toggle="tab"    .tabbable(容器)   .tabs-left (right , below)   .tab-content

注意： .dropdown-submenu(多級導航中，可能bootstrap中沒有)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>

添加這段css即可使.dropdown-submenu有效

實現(xiàn)菜單樣式：

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>無標題文檔</title>
<script type="text/javascript" src="bootstrap-3.3.6/js/jquery.cyan1.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;
  }
