Any widget can be transformed into tabbed one just by adding .widget-tabs
class and
providing appropriate markup for tabs. For example:
<section class="widget widget-tabs">
<header>
<ul class="nav nav-tabs">
<li class="active"><a href="#stats" data-toggle="tab">One</a></li>
<li><a href="#report" data-toggle="tab">Two</a></li>
</ul>
</header>
<div class="body tab-content">
<div id="stats" class="tab-pane active">
Some text
</div>
<div id="report" class="tab-pane">
Some text 2
</div>
</div>
</section>
Tabs can also be included not just as widget header but anywhere. Read more about Bootstrap tabs
