Bootstrap JS Tab
JS Tab (tab.js)
Tabs are used to separate content into different panes where each pane is viewable one at a time.
For a tutorial about Tabs, read our Bootstrap Tabs/Pills Tutorial.
The Tab Plugin Classes
| Class | Description | Example |
| .nav nav-tabs | Creates navigation tabs |
|
| .nav-justified | Makes navigation tabs/pills equal widths of their parent, at screens wider than 768px. On smaller screens, the nav tabs are stacked |
|
| .tab-content | Together with .tab-pane and data-toggle="tab", it makes the tab toggleable |
|
| .tab-pane | Together with .tab-content and data-toggle="tab", it makes the tab toggleable |
|
Via data-* Attributes
Add
data-toggle="tab" to each tab, and add a
.tab-pane class with a unique ID for every tab and wrap them in a
.tab-content class.
Example
<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#home">Home</a></li>
<li><a data-toggle="tab" href="#menu1">Menu 1</a></li>
</ul>
<div class="tab-content">
<div id="home" class="tab-pane fade in active">
<h3>HOME</h3>
<p>Some content.</p>
</div>
<div id="menu1" class="tab-pane fade">
<h3>Menu 1</h3>
<p>Some content in menu 1.</p>
</div>
</div>
