Various embodiments related to assigning z-order to a plurality of user interface elements are disclosed. One disclosed embodiment provides a method of assigning a z-ordering to a user interface element displayed on a multi-user interactive display based upon an interaction state of the user interface element, the interaction state being dependent upon how a user interacts with the user interface element. The method comprises detecting a change in the interaction state of the user interface element. If the change is an initiation of a movement of the user interface element on the display, the user interface element is moved to a first predetermined position within the z-ordering. If the change is an initiation of a user interaction with content contained within the user interface element, the user interface element is moved to a second predetermined position within the z-ordering.
