Bootstrap 4 Button Groups
Button Groups
Bootstrap 4 allows you to group a series of buttons together (on a single line) in a button group:
Use a <div> element with class .btn-group to create a button group:
Example
<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>

Tip: Instead of applying button sizes to every button in a
group, use class .btn-group-lg for a large button group or the .btn-group-sm for a small button group:
Large Buttons:
Default Buttons:
Small Buttons:
Example
<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>

Vertical Button Groups
Bootstrap 4 also supports vertical button groups:

<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>

Button Groups Side by Side
Button groups are "inline" by default, which makes them appear side by side when you have multiple groups:
Example
<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>
<div class="btn-group">
<button type="button" class="btn btn-primary">BMW</button>
<button type="button" class="btn btn-primary">Mercedes</button>
<button type="button" class="btn btn-primary">Volvo</button>
</div>
