Tab

Create horizontal tab navigations and vertical nativations easily.

Introduction

The tab component includes two parts, tab indicators and tab panes. Tab panes are used to wrap contents, and tab indicators are used to control which tab pane to show. A tab can be created with these classes: .tab, .tab-indicators, .tab-panes and .tab-pane.

Vertical Tab

To create a vertical tab navigation, add the class .tab to a container, then wrap tab indicators and tab panes like the below example.

Once upon time a girl named Cinderella lived with her stepmother and two stepsisters. Poor Cinderella had to work hard all day long so the others could rest...

It was she who had to wake up each morning when it was still dark and cold to start the fire. It was she who cooked the meals...

It was she who kept the fire going. The poor girl could not stay clean, from all the ashes and cinders by the fire...

Horizontal Tab

To create a horizontal tab navigation, a .grid need be wrapped in the .tab container. Let’s see the below example for detail.
