Tray 
The Tray UI element (IWDTray) is a UI element container like the Group UI element container and can be used to group a set of UI elements under one common title. Unlike the Group UI element it provides additional functions. For example, the Tray UI element can be displayed or hidden.
Examples of the Display
|
Tray with Design Plain
Tray with Design Fill and Menu
Collapsed Tray with Transparent Design
|

If the property caption has not been set, the property accessibilityDescription is checked during the design time to ensure Accessibility.
The property tooltip is not checked.
A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it, if it contains detailed semantic information.
