前言

一、资源

Ref: http://www.runoob.com/try/bootstrap/layoutit/【拖拽布局】

本篇讲得是：布局组件。

菜单、按钮及导航组件

一、菜单

综合示范

<body>
<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown">
    下拉菜单
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">

    <li role="presentation" class="dropdown-header">第一部分菜单头部</li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation" class="divider"></li>

    <li role="presentation" class="dropdown-header">第二部分菜单头部</li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
  </ul>
</div> 
  <script src="https://www.imooc.com/static/lib/jquery/1.9.1/jquery.js"></script>　　　　　　# ----> 注释A
  <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script> 

</body>

注释A:

特别声明：因为Bootstrap的组件交互效果都是依赖于jQuery库写的插件，

所以在使用bootstrap.min.js之前一定要先加载jquery.min.js 才会生效果。

item 按键状态

  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
    <li role="presentation" class="active">  <a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation">                 <a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
    <li role="presentation">                 <a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>

    <li role="presentation" class="divider"></li>

    <li role="presentation" class="disabled"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
  </ul>

按钮等价效果

<body>
  <div class="btn-group">
      <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">按钮下拉菜单<span class="caret"></span></button>
    <ul class="dropdown-menu">
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
    </ul>
  </div>
  <script src="https://www.imooc.com/static/lib/jquery/1.9.1/jquery.js"></script>
  <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script> 
</body>

按钮向上弹出菜单

<body>
<div class="btn-group dropup">
    <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">按钮下拉菜单<span class="caret"></span></button>
    <ul class="dropdown-menu">
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
        <li><a href="##">按钮下拉菜单项</a></li>
    </ul>
</div>
  <script src="https://www.imooc.com/static/lib/jquery/1.9.1/jquery.js"></script>
  <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script> 
</body>
