An operating system for a vehicle, wherein the operating system comprises -- a display device with a display area, -- a memory device for storing list elements (11, 11') and elements which are assigned to the list elements (11, 11'), -- an input element for selecting a list element by a user, and -- a control device which is coupled to the display device and the input element and with which a reproducing display on the display area can be controlled, wherein the control device is configured to control the display area such that in a first display mode at least some of the list elements are displayed on the display area in the form of a list and that by selecting a list element a change from the first display mode to a second display mode is realised, wherein during the change an animated opening movement is generated in which -- a displaying area is released by enlarging a display area region assigned to the selected list element and the further list elements neighbouring the selected list element are displaced until all further list elements are displaced from the display area by the displaying area and -- the displaying area is provided for the reproducing display of at least one associated element of the selected list element, in particular in the form of an information window, wherein the control device is further configured to control the display area such that in the second display mode a single element is displayed in the form of a single information window, and to control the display area such that in the first display mode a change between the list elements (11, 11') and in the second display mode a change between the elements of the selected list element is realised by a scrolling functionality; and wherein the elements assigned to a list element are sorted in a list with a list start and a list end, wherein the operating system is designed in such a way that a soft stop is provided at the list start and/or at the list end, wherein overcoming the soft stop when reaching the list start and/or the list end triggers a direct return to the first display mode. -- a display device with a display area, -- a memory device for storing list elements (11, 11') and elements which are assigned to the list elements (11, 11'), -- an input element for selecting a list element by a user, and -- a control device which is coupled to the display device and the input element and with which a reproducing display on the display area can be controlled, wherein the control device is configured to control the display area such that in a first display mode at least some of the list elements are displayed on the display area in the form of a list and that by selecting a list element a change from the first display mode to a second display mode is realised, wherein during the change an animated opening movement is generated in which -- a displaying area is released by enlarging a display area region assigned to the selected list element and the further list elements neighbouring the selected list element are displaced until all further list elements are displaced from the display area by the displaying area and -- the displaying area is provided for the reproducing display of at least one associated element of the selected list element, in particular in the form of an information window, wherein the control device is further configured to control the display area such that in the second display mode a single element is displayed in the form of a single information window, and to control the display area such that in the first display mode a change between the list elements (11, 11') and in the second display mode a change between the elements of the selected list element is realised by a scrolling functionality; and wherein the elements assigned to a list element are sorted in a list with a list start and a list end, wherein the operating system is designed in such a way that a soft stop is provided at the list start and/or at the list end, wherein overcoming the soft stop when reaching the list start and/or the list end triggers a direct return to the first display mode.
