Bootstrap4(9): 按钮组
一、创建按钮组
Bootstrap 4 中允许我们将按钮放在同一行上。
可以在
元素上添加 .btn-group 类来创建按钮组。
<div class="btn-group"> <button type="button" class="btn btn-primary">Apple</button> <button type="button" class="btn btn-primary">Samsung</button> <button type="button" class="btn btn-primary">Sony</button> </div>
提示: 我们可以使用 .btn-group-lg|sm 类来设置按钮组的大小。
<div class="btn-group btn-group-lg"> <button type="button" class="btn btn-primary">Apple</button> <button type="button" class="btn btn-primary">Samsung</button> <button type="button" class="btn btn-primary">Sony</button> </div>
二、垂直按钮组
可以使用 .btn-group-vertical 类来创建垂直的按钮组:
<div class="btn-group-vertical"> <button type="button" class="btn btn-primary">Apple</button> <button type="button" class="btn btn-primary">Samsung</button> <button type="button" class="btn btn-primary">Sony</button> </div>
三、内嵌按钮组及下拉菜单
我们可以在按钮组内设置下拉菜单:
<div class="btn-group"> <button type="button" class="btn btn-primary">Apple</button> <button type="button" class="btn btn-primary">Samsung</button> <div class="btn-group"> <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"> Sony </button> <div class="dropdown-menu"> <a class="dropdown-item" href="#">Tablet</a> <a class="dropdown-item" href="#">Smartphone</a> </div> </div> </div>
四、拆分按钮下拉菜单
<div class="btn-group"> <button type="button" class="btn btn-primary">Sony</button> <button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-toggle="dropdown"> <span class="caret"></span> </button> <div class="dropdown-menu"> <a class="dropdown-item" href="#">Tablet</a> <a class="dropdown-item" href="#">Smartphone</a> </div> </div>
五、垂直按钮组及下拉菜单
<div class="btn-group-vertical"> <button type="button" class="btn btn-primary">Apple</button> <button type="button" class="btn btn-primary">Samsung</button> <div class="btn-group"> <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"> Sony </button> <div class="dropdown-menu"> <a class="dropdown-item" href="#">Tablet</a> <a class="dropdown-item" href="#">Smartphone</a> </div> </div> </div>
