A header combines the functionality of a page title and a control bar for your page. Due to its compact design and versatility it is often used in mobile pages. As a lay-out feature it can only be used in a layout.

Headers consist of three distinct elements: a left drop-zone, a right drop-zone, and a page title. The drop-zones are intended for confirmation buttons, such as a save and cancel button, but can easily be appropriated for any number of alternate implementations. The page title derives its value from the page title setting of the page being displayed.
