InvisibleElement 

The InvisibleElement UI element represents an invisible element. It can be used to fill an empty cell in GridLayout or in MatrixLayout. It can also be used as a placeholder if a UI element is created dynamically. The UI element inherits properties from its superordinate classes UIElement and ViewElement. However, the enabled, tooltip, and visible properties are ignored and have no visual effects in the browser.

The enabled, tooltip, and visible properties are inherited from the CL_WD_UIELEMENT (UIElement) base class but have no effect for this UI element.

To enable the development of accessible applications, the tooltip property is not checked during the syntax check because a tooltip would not be useful for this UI element.
