按钮组

将一系列按钮组合在同一行上，或将它们堆叠在垂直列中。

本页目录

基本示例

用...包裹一系列按钮 .btn 在 .btn-group.

HTML
<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-primary">Left</button>
  <button type="button" class="btn btn-primary">Middle</button>
  <button type="button" class="btn btn-primary">Right</button>
</div>

按钮组需要一个合适的 role 属性和明确的标签，以确保辅助技术（如屏幕阅读器）能够识别按钮为组并正确朗读它们。对于按钮组使用 role="group"，或者对于按钮工具栏使用 role="toolbar"。然后使用 aria-label 或 aria-labelledby 来为它们添加标签。

这些类也可以添加到链接组中，作为.nav导航组件的替代方案。

活动链接 链接 链接
HTML
<div class="btn-group">
  <a href="#" class="btn btn-primary active" aria-current="page">Active link</a>
  <a href="#" class="btn btn-primary">Link</a>
  <a href="#" class="btn btn-primary">Link</a>
</div>

混合风格

HTML
<div class="btn-group" role="group" aria-label="Basic mixed styles example">
  <button type="button" class="btn btn-danger">Left</button>
  <button type="button" class="btn btn-warning">Middle</button>
  <button type="button" class="btn btn-success">Right</button>
</div>

轮廓样式

HTML
<div class="btn-group" role="group" aria-label="Basic outlined example">
  <button type="button" class="btn btn-outline-primary">Left</button>
  <button type="button" class="btn btn-outline-primary">Middle</button>
  <button type="button" class="btn btn-outline-primary">Right</button>
</div>

复选框和单选按钮组

将按钮样式的复选框和单选按钮 切换按钮 组合成一个无缝的按钮组。

HTML
<div class="btn-group" role="group" aria-label="Basic checkbox toggle button group">
  <input type="checkbox" class="btn-check" id="btncheck1" autocomplete="off">
  <label class="btn btn-outline-primary" for="btncheck1">Checkbox 1</label>

<input type="checkbox" class="btn-check" id="btncheck2" autocomplete="off">
<label class="btn btn-outline-primary" for="btncheck2">Checkbox 2</label>


<input type="checkbox" class="btn-check" id="btncheck3" autocomplete="off">
<label class="btn btn-outline-primary" for="btncheck3">Checkbox 3</label>
</div>

HTML
<div class="btn-group" role="group" aria-label="Basic radio toggle button group">
  <input type="radio" class="btn-check" name="btnradio" id="btnradio1" autocomplete="off" checked>
  <label class="btn btn-outline-primary" for="btnradio1">Radio 1</label>

<input type="radio" class="btn-check" name="btnradio" id="btnradio2" autocomplete="off">
<label class="btn btn-outline-primary" for="btnradio2">Radio 2</label>


<input type="radio" class="btn-check" name="btnradio" id="btnradio3" autocomplete="off">
<label class="btn btn-outline-primary" for="btnradio3">Radio 3</label>
</div>

按钮工具栏

将一组按钮组合成按钮工具栏，以创建更复杂的组件。根据需要使用工具类来调整组、按钮等之间的间距。

HTML
<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group me-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-primary">1</button>
    <button type="button" class="btn btn-primary">2</button>
    <button type="button" class="btn btn-primary">3</button>
    <button type="button" class="btn btn-primary">4</button>
  </div>
  <div class="btn-group me-2" role="group" aria-label="Second group">
    <button type="button" class="btn btn-secondary">5</button>
    <button type="button" class="btn btn-secondary">6</button>
    <button type="button" class="btn btn-secondary">7</button>
  </div>
  <div class="btn-group" role="group" aria-label="Third group">
    <button type="button" class="btn btn-info">8</button>
  </div>
</div>

在工具栏中随意混合输入组和按钮组。类似于上面的例子，你可能仍然需要一些工具类来正确安排间距。

HTML
<div class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group me-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-outline-secondary">1</button>
    <button type="button" class="btn btn-outline-secondary">2</button>
    <button type="button" class="btn btn-outline-secondary">3</button>
    <button type="button" class="btn btn-outline-secondary">4</button>
  </div>
  <div class="input-group">
    <div class="input-group-text" id="btnGroupAddon">@</div>
    <input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon">
  </div>
</div>

<div class="btn-toolbar justify-content-between" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group" role="group" aria-label="First group">
<button type="button" class="btn btn-outline-secondary">1</button>
<button type="button" class="btn btn-outline-secondary">2</button>
<button type="button" class="btn btn-outline-secondary">3</button>
<button type="button" class="btn btn-outline-secondary">4</button>
</div>
<div class="input-group">
<div class="input-group-text" id="btnGroupAddon2">@</div>
<input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon2">
</div>
</div>

尺寸

与其在组中的每个按钮上应用按钮大小类，不如将.btn-group-*添加到每个.btn-group，包括在嵌套多个组时的每一个按钮。



HTML
<div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
  <button type="button" class="btn btn-outline-primary">Left</button>
  <button type="button" class="btn btn-outline-primary">Middle</button>
  <button type="button" class="btn btn-outline-primary">Right</button>
</div>
<br>
<div class="btn-group" role="group" aria-label="Default button group">
  <button type="button" class="btn btn-outline-primary">Left</button>
  <button type="button" class="btn btn-outline-primary">Middle</button>
  <button type="button" class="btn btn-outline-primary">Right</button>
</div>
<br>
<div class="btn-group btn-group-sm" role="group" aria-label="Small button group">
  <button type="button" class="btn btn-outline-primary">Left</button>
  <button type="button" class="btn btn-outline-primary">Middle</button>
  <button type="button" class="btn btn-outline-primary">Right</button>
</div>

嵌套

当你想将下拉菜单与一系列按钮混合使用时，请将.btn-group放入另一个.btn-group中。

HTML
<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
  <button type="button" class="btn btn-primary">1</button>
  <button type="button" class="btn btn-primary">2</button>

<div class="btn-group" role="group">
<button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
Dropdown
</button>
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Dropdown link</a></li>
<li><a class="dropdown-item" href="#">Dropdown link</a></li>
</ul>
</div>
</div>

垂直变化

让一组按钮垂直堆叠显示，而不是水平显示。此处不支持分割按钮下拉菜单。

HTML
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
  <button type="button" class="btn btn-primary">Button</button>
  <button type="button" class="btn btn-primary">Button</button>
  <button type="button" class="btn btn-primary">Button</button>
  <button type="button" class="btn btn-primary">Button</button>
</div>
HTML
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
  <div class="btn-group" role="group">
    <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
      Dropdown
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
    </ul>
  </div>
  <button type="button" class="btn btn-primary">Button</button>
  <button type="button" class="btn btn-primary">Button</button>
  <div class="btn-group dropstart" role="group">
    <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
      Dropdown
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
    </ul>
  </div>
  <div class="btn-group dropend" role="group">
    <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
      Dropdown
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
    </ul>
  </div>
  <div class="btn-group dropup" role="group">
    <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
      Dropdown
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
      <li><a class="dropdown-item" href="#">Dropdown link</a></li>
    </ul>
  </div>
</div>
HTML
<div class="btn-group-vertical" role="group" aria-label="Vertical radio toggle button group">
  <input type="radio" class="btn-check" name="vbtn-radio" id="vbtn-radio1" autocomplete="off" checked>
  <label class="btn btn-outline-danger" for="vbtn-radio1">Radio 1</label>
  <input type="radio" class="btn-check" name="vbtn-radio" id="vbtn-radio2" autocomplete="off">
  <label class="btn btn-outline-danger" for="vbtn-radio2">Radio 2</label>
  <input type="radio" class="btn-check" name="vbtn-radio" id="vbtn-radio3" autocomplete="off">
  <label class="btn btn-outline-danger" for="vbtn-radio3">Radio 3</label>
