这里注意的是我们需要将boot下载的font文件夹包含在工程中才能正常使用
这里我们必须先下载组件文件bootstrap-dropdown.js才能正常的使用这个功能
演示代码:
<link rel="stylesheet" href="css/bootstrap.min.css">
<script type="text/javascript" src="js/jquery-1.7.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript" src="js/bootstrap-dropdown.js"></script>
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
测试
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
按钮组
对按键进行分组管理
演示代码:
<div class="btn-group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
尺寸:
<div class="btn-group btn-group-lg">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
<div class="btn-group btn-group-xs">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
垂直:
<div class="btn-group-vertical">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
单按钮下拉菜单:
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Action <span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
分裂式——注意在使用这个的时候<!DOCTYPE html>只能是这样才可以
<div class="btn-group">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
