Detailed Description

PageRow implements a row-based navigation model, which can be used with a set of interlinked information pages.

Pages are pushed in the back of the row and the view scrolls until that row is visualized. A PageRow can show a single page or a multiple set of columns, depending on the window width: on a phone a single column should be fullscreen, while on a tablet or a desktop more than one column should be visible.
