Bootstrap Button Group

A Button group is an easy way to group a series of buttons together. Bootstrap allows to group a series of buttons within a single line or place them in a vertical stack. This button group is used to place multiple buttons with different functions within a webpage. Let's understand how to create a button group.

  • Wrap a series of buttons within the .btn-group class
  • Add .btn class within <button> tag to add each button.
  • We can add customized buttons with a button utility class.
  • To convey to screen readers that the button is grouped, the button groups are provided with role=group.
  • The button group should also be provided with explicit labels within the aria-label or aria-labelledby attribute.

Example: Creating a group of buttons

So lets us create a series of buttons using the button group class of bootstap5.

Checkbox and radio button groups

A button group can act as a checkbox as well as radio buttons. Let's see how we can add a checkbox and radio button functionality to a button group.

  • Add <input>s and <label>s element within the button group class.
  • Within <input> add type="checkbox" for checkbox and for radio buttons use type="radio"
  • Also add .btn-check class within <input> element.
  • id is added to the <input> element with some unique name.
  • In addition to that radio button has a name attribute within <input> where we can assign some names to the radio buttons. Remember to keep it the same for all radio buttons.
  • <label> element consist .btn class customized with some button utility class and for attribute pointing to the id attribute.

Example: Adding checkbox and radio button to button group class

Here, we have added checkboxes and radio buttons to the button group class. The buttons have been customized with the .btn-outline class.

Button Toolbar

The series of buttons can also be used as a toolbar for some more complex functions using button groups. Button toolbar should be included within the .button-toolbar class and role should be assigned with role=toolbar.

Example: Creating a button toolbar using the button group

As stated above the .btn-group class can be added within the .btn-toolbar to create a button toolbar. You can add a button utility class to customize these buttons.

Nesting Button Group

The button group can be nested within another button group. The dropdown menu can be used within the nested button group.
