|
## Basic example
|
|
|
|
Wrap a series of buttons with `.btn` in `.btn-group`.
|
|
|
|
{% example html %}
|
|
<div class="btn-group" role="group" aria-label="Basic example">
|
|
<button type="button" class="btn btn-secondary">Left</button>
|
|
<button type="button" class="btn btn-secondary">Middle</button>
|
|
<button type="button" class="btn btn-secondary">Right</button>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
## Button toolbar
|
|
|
|
Combine sets of button groups into button toolbars for more complex components.
|
|
|
|
{% example html %}
|
|
<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
|
|
<div class="btn-group" role="group" aria-label="First group">
|
|
<button type="button" class="btn btn-secondary">1</button>
|
|
<button type="button" class="btn btn-secondary">2</button>
|
|
<button type="button" class="btn btn-secondary">3</button>
|
|
<button type="button" class="btn btn-secondary">4</button>
|
|
</div>
|
|
<div class="btn-group" 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-secondary">8</button>
|
|
</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
## Sizing
|
|
|
|
Instead of applying button sizing classes to every button in a group, just add `.btn-group-*` to each `.btn-group`, including each one when nesting multiple groups.
|
|
|
|
<div class="bd-example">
|
|
<div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
|
|
<button type="button" class="btn btn-secondary">Left</button>
|
|
<button type="button" class="btn btn-secondary">Middle</button>
|
|
<button type="button" class="btn btn-secondary">Right</button>
|
|
</div>
|
|
<br>
|
|
<div class="btn-group" role="group" aria-label="Default button group">
|
|
<button type="button" class="btn btn-secondary">Left</button>
|
|
<button type="button" class="btn btn-secondary">Middle</button>
|
|
<button type="button" class="btn btn-secondary">Right</button>
|
|
</div>
|
|
<br>
|
|
<div class="btn-group btn-group-sm" role="group" aria-label="Small button group">
|
|
<button type="button" class="btn btn-secondary">Left</button>
|
|
<button type="button" class="btn btn-secondary">Middle</button>
|
|
<button type="button" class="btn btn-secondary">Right</button>
|
|
</div>
|
|
</div>
|
|
|
|
{% highlight html %}
|
|
<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
|
|
<div class="btn-group" role="group" aria-label="...">...</div>
|
|
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>
|
|
{% endhighlight %}
|
|
|
|
## Nesting
|
|
|
|
Place a `.btn-group` within another `.btn-group` when you want dropdown menus mixed with a series of buttons.
|
|
|
|
{% example html %}
|
|
<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
|
|
<button type="button" class="btn btn-secondary">1</button>
|
|
<button type="button" class="btn btn-secondary">2</button>
|
|
|
|
<div class="btn-group" role="group">
|
|
<button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown
|
|
</button>
|
|
<div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
## Vertical variation
|
|
|
|
Make a set of buttons appear vertically stacked rather than horizontally. **Split button dropdowns are not supported here.**
|
|
|
|
<div class="bd-example">
|
|
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
|
|
<button type="button" class="btn btn-secondary">Button</button>
|
|
<button type="button" class="btn btn-secondary">Button</button>
|
|
<div class="btn-group" role="group">
|
|
<button id="btnGroupVerticalDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown
|
|
</button>
|
|
<div class="dropdown-menu" aria-labelledby="btnGroupVerticalDrop1">
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
</div>
|
|
</div>
|
|
<button type="button" class="btn btn-secondary">Button</button>
|
|
<button type="button" class="btn btn-secondary">Button</button>
|
|
<div class="btn-group" role="group">
|
|
<button id="btnGroupVerticalDrop2" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown
|
|
</button>
|
|
<div class="dropdown-menu" aria-labelledby="btnGroupVerticalDrop2">
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
</div>
|
|
</div>
|
|
<div class="btn-group" role="group">
|
|
<button id="btnGroupVerticalDrop3" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown
|
|
</button>
|
|
<div class="dropdown-menu" aria-labelledby="btnGroupVerticalDrop3">
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
</div>
|
|
</div>
|
|
<div class="btn-group" role="group">
|
|
<button id="btnGroupVerticalDrop4" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown
|
|
</button>
|
|
<div class="dropdown-menu" aria-labelledby="btnGroupVerticalDrop4">
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
<a class="dropdown-item" href="#">Dropdown link</a>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
|
|
{% highlight html %}
|
|
<div class="btn-group-vertical">
|
|
...
|
|
</div>
|
|
{% endhighlight %}
|
|
|
|
## Tooltips and popovers
|
|
|
|
Due to the specific implementation (and some other components), a bit of special casing is required for tooltips and popovers within button groups. **You'll have to specify the option `container: 'body'`** to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
