How to Create Dynamic Tabs in Bootstrap ?

Last Updated : 29 Apr, 2024

Bootstrap's dynamic tabs empower web developers by enabling on-demand tab creation. This feature enhances user experience by facilitating dynamic content presentation within a tabbed interface. Admins can effortlessly generate tabs as needed, enriching site interactivity.

Tabs in Bootstrap are navigational components that organize content into separate panes, allowing users to switch between them easily.

Approach

Create an HTML document and add the necessary Bootstrap 5 CDN links.
Create the basic structure which includes a navigation bar, a container for tabs, and a container for tab content.
Create a button to add new tabs dynamically.
Create a JavaScript file and link it to the HTML file using script tag.
Create a function in JS to add new tabs whenever the button is pressed. Name of the tab should be asked from the user through alerts. The tag content area should also be created at the same time.
Create a function in JS to show the currently active tab by using the 'active' class of Bootstrap.

Example: The example below illustrates the implementation to create dynamic tabs in Bootstrap through above approach.
