Bootstrap
按钮组
按钮组允许多个按钮被堆叠在同一行上。当你想要把按钮对齐在一起时，这就显得非常有用。您可以通过
Bootstrap 按钮（Button） 插件
添加可选的 JavaScript 单选框和复选框样式行为。
下面的表格总结了 Bootstrap 提供的使用按钮组的一些重要的 class：

描述

代码示例
|
|
.btn-group
|
该 class 用于形成基本的按钮组。在
.btn-group
中放置一系列带有 class
.btn
的按钮。
|
<div class="btn-group">
<button type="button" class="btn btn-default">Button1</button>
<button type="button" class="btn btn-default">Button2</button>
</div>
|
|
.btn-toolbar
|
该 class 有助于把几组 <div class="btn-group"> 结合到一个 <div class="btn-toolbar"> 中，一般获得更复杂的组件。
|
<div class="btn-toolbar" role="toolbar">
<div class="btn-group">...</div>
<div class="btn-group">...</div>
</div>
|
|
.btn-group-lg, .btn-group-sm, .btn-group-xs
|
这些 class 可应用到整个按钮组的大小调整，而不需要对每个按钮进行大小调整。
|
<div class="btn-group btn-group-lg">...</div>
<div class="btn-group btn-group-sm">...</div>
<div class="btn-group btn-group-xs">...</div>
|
|
.btn-group-vertical
|
该 class 让一组按钮垂直堆叠显示，而不是水平堆叠显示。
|
<div class="btn-group-vertical">
...
</div>
|

嵌套
您可以在一个按钮组内嵌套另一个按钮组，即，在一个
.btn-group
内嵌套另一个
.btn-group
。当您想让下拉菜单与一系列按钮组合使用时，就会用到这个。
