Top tab panel is powered by jQuery and is a flexible panel which can contain anything you can put in as block. The height of the panel is automatically adjusted to its content. Tab title can be customized in the theme setting for both anonymous and logged in user.

The tab panel is holding 3 block regions to provide greater flexibility. As with other block regions, the tab is hidden when no block is assigned to any of the 3 regions in the tab panel.

Example use cases are:

• Login panel for anonymous user, and user account panel after user is logged in.
• Search panel.
• Special content such as promotion.
