If a TActionClientItem is used to represent a category of actions and not just a single action, the Items property is automatically set to the TActionClients object that contains the sub-items by the action manager. An example of this would be when an action category such as the standard actions "Edit" category is placed on a main menu action band. The Items property would contain the standard actions such as TEditCopy, TEditPaste, and TEditCut in a TActionClients object.
