One of the essential components of Bootstrap 5 is the button group, which helps in grouping buttons for better user experience and design consistency. In this article, we will explore the different functionalities of button groups in Bootstrap 5, including basic examples, vertical alignment, nesting, and more.
I. Introduction
A. Overview of Bootstrap 5
Bootstrap 5 is the latest version of the widely-used CSS framework designed for building responsive and mobile-first websites. It includes various pre-designed components such as buttons, forms, navigation bars, and modals, simplifying the development process.
B. Importance of button groups in web design
Button groups are crucial for enhancing the usability and aesthetics of web applications. They provide a way to group related actions visually, making it easier for users to understand the options available to them.
II. Basic Example
A. How to create a simple button group
A basic button group can be created easily by using Bootstrap’s predefined classes. The buttons within the group are styled to look like a single button with distinct segments.
B. Code example and explanation
<div class="btn-group" role="group" aria-label="Basic example"> <button type="button" class="btn btn-primary">Button 1</button> <button type="button" class="btn btn-primary">Button 2</button> <button type="button" class="btn btn-primary">Button 3</button> </div>
This code creates a horizontal group of buttons labeled “Button 1”, “Button 2”, and “Button 3”. Each button is styled with the btn-primary class to have a blue background.
III. Vertical Button Group
A. Creating a vertical button group
To create a vertical button group, you can add a class to stack the buttons vertically instead of horizontally.
B. Code example and explanation
<div class="btn-group-vertical" role="group" aria-label="Vertical button group"> <button type="button" class="btn btn-secondary">Button A</button> <button type="button" class="btn btn-secondary">Button B</button> <button type="button" class="btn btn-secondary">Button C</button> </div>
This example creates a vertical button group with three buttons styled using the btn-secondary class.
IV. Button Group Nesting
A. How to nest button groups
You can nest button groups within other button groups to create more complex layouts and options.
B. Code example and explanation
<div class="btn-group" role="group">
<button type="button" class="btn btn-danger">Main Button</button>
<div class="btn-group" role="group">
<button type="button" class="btn btn-success">Nested Button 1</button>
<button type="button" class="btn btn-success">Nested Button 2</button>
</div>
</div>
This code demonstrates a main button labeled “Main Button” with a nested button group containing “Nested Button 1” and “Nested Button 2”.
V. Button Toolbar
A. Introduction to button toolbars
A button toolbar is a collection of button groups that can be aligned to create a more structured layout.
B. Code example and explanation
<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group me-2" role="group">
<button type="button" class="btn btn-outline-secondary">1</button>
<button type="button" class="btn btn-outline-secondary">2</button>
</div>
<div class="btn-group me-2" role="group">
<button type="button" class="btn btn-outline-secondary">3</button>
<button type="button" class="btn btn-outline-secondary">4</button>
</div>
<div class="btn-group" role="group">
<button type="button" class="btn btn-outline-secondary">5</button>
</div>
</div>
This toolbar example contains three groups: the first group has buttons labeled “1” and “2”, the second group has buttons labeled “3” and “4”, and the third group has button “5”.
VI. Sizing Button Groups
A. Different sizes for button groups
You can modify the size of button groups using predefined classes for small, large, or default sizes.

This button group showcases three different sizes: a large, default, and small button, allowing for varying layouts.
VII. Justified Button Groups
A. Aligning buttons equally in a group
Justified button groups ensure that all buttons occupy equal widths, providing a balanced look.
B. Code example and explanation
<div class="btn-group w-100" role="group"> <button type="button" class="btn btn-info w-100">Button 1</button> <button type="button" class="btn btn-warning w-100">Button 2</button> <button type="button" class="btn btn-danger w-100">Button 3</button> </div>
