按鈕組

將一系列按鈕組合在一行上或將它們堆疊在垂直列中。

在本頁面

基本示例

.btn用in包裹一系列按鈕.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>
確保正確role並提供標籤

為了讓輔助技術（例如屏幕閱讀器）傳達一系列按鈕被分組的意思，role需要提供適當的屬性。對於按鈕組，這將是role="group"，而工具欄應該有role="toolbar".

此外，組和工具欄應該被賦予明確的標籤，因為大多數輔助技術不會公佈它們，儘管存在正確的角色屬性。在此處提供的示例中，我們使用，但也可以使用aria-label替代方法，例如。aria-labelledby

這些類也可以添加到鏈接組中，作為.nav導航組件的替代方案。

活動鏈接 關聯 關聯
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>

混合風格

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>

輪廓樣式

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>

複選框和單選按鈕組

將類似按鈕的複選框和單選切換按鈕組合成一個外觀無縫的按鈕組。

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>

按鈕工具欄

將多組按鈕組組合成按鈕工具欄以實現更複雜的組件。根據需要使用實用程序類來分隔組、按鈕等。

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>

隨意將輸入組與工具欄中的按鈕組混合。與上面的示例類似，您可能需要一些實用程序來正確分隔事物。

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>

漿紗

無需將按鈕大小調整類應用於組中的每個按鈕，只需添加.btn-group-*到每個按鈕.btn-group，包括嵌套多個組時的每個按鈕。



html 
<div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
  <button type="button" class="btn btn-outline-dark">Left</button>
  <button type="button" class="btn btn-outline-dark">Middle</button>
  <button type="button" class="btn btn-outline-dark">Right</button>
</div>
<br>
<div class="btn-group" role="group" aria-label="Default button group">
  <button type="button" class="btn btn-outline-dark">Left</button>
  <button type="button" class="btn btn-outline-dark">Middle</button>
  <button type="button" class="btn btn-outline-dark">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-dark">Left</button>
  <button type="button" class="btn btn-outline-dark">Middle</button>
  <button type="button" class="btn btn-outline-dark">Right</button>
</div>

嵌套

當您希望下拉菜單與一系列按鈕混合時，將 a.btn-group放在另一個中。.btn-group

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>

垂直變化

使一組按鈕顯示為垂直堆疊而不是水平堆疊。此處不支持拆分按鈕下拉菜單。

html 
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
  <button type="button" class="btn btn-dark">Button</button>
  <button type="button" class="btn btn-dark">Button</button>
  <button type="button" class="btn btn-dark">Button</button>
  <button type="button" class="btn btn-dark">Button</button>
  <button type="button" class="btn btn-dark">Button</button>
  <button type="button" class="btn btn-dark">Button</button>
</div>
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>
  <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" 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" 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" 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">
