InvisibleElement 

The UI element InvisibleElement is an invisible element on the screen. It can be used to fill an empty cell in the GridLayout or in the MatrixLayout. It can also be used as a placeholder, if a UI element is created dynamically. The UI element inherits the properties from it superclass UI element and ViewElement. The properties enabled, tooltip, and visible are however ignored and do not affect the browser.

The properties enabled, tooltip and visible are inherited by the base class CL_WD_UIELEMENT (UIElement), but they do not have any affect on this UI element.

In the design time the tooltip is not checked to ensure Accessibility, since there is no use for a tooltip with this UI element.
