This tutorial highlights the use of Bootstrap tab plugin for the navigation. In general, the term tab allows for the user to access different parts of the menu or webpage. We can create dynamic tabs by clicking on tabbable areas or navigation panes to navigate to contents on the webpage. The most often used navigation is tab based navigation which contains large amount of data within small area separating content into different navigation panes where each pane can be view able one at a time.
The tab plugin provided by Bootstrap can be used to access content in tabs or pills or even through dropdown menu. For more information about tab based navigation, just refer this link: Bootstrap Navigation Elements.

We can create tabbable tabs by using following two ways:
- Via Data Attributes
- Via JavaScript
Bootstrap Tabs via Data Attributes
We can create tab component by using data-toggle=”tab” on each tab within an anchor tab. We are using the tab-content class as the parent element and tab-pane class to create tabs via data attributes. We are creating tab-pane for every tab with unique ID and wrapping them within tab-content class. While switching from one tab to another tab, to get fade effect for tabs, add the .fade class to each .tab-pane class.
The following is an example:
[code lang=”xml”]
<!DOCTYPE html>
<head>
