Definition and Usage

The Form control defines a container for mobile controls.

Each mobile page must have at least one Form control, and each Form control can have a number of mobile controls.

Note that mobile pages can have multiple Form controls. This is due to the nature of mobile devices. Mobile devices have small screens and it is very normal to navigate between screens with simple links.
