Controls in a ControlGroup container are rendered using a mobile style.
Controls inside a ControlGroup container are rendered using a style that is common on mobile applications. The ControlGroup container is typically used in UX Components that users Panels.
The style applied removes the border from the input controls and adds a divider line that separates each control.
The ControlGroup container is not supported in applications using version 4 (e.g. 'Alpha' or themes that inherit from 'Alpha') or newer styles.
