A graphical user interface for a display devised for presentation of hierarchical information, comprising a first menu field (1) carrying a list of menu items (2), at least one of said menu items indicating a submenu field which is expandable within said first menu field. A graphical layer effect (4) is applied to an expanded submenu field such that said submenu field is displayed as an underlying layer (3) to the first menu field. Said graphical effect may comprise the visualisation of an edge (4) between displayed layers or a shadow (4) on an underlying layer from an overlying layer. Preferably, an expanded submenu field, located between two menu items, the first menu field is displayed as being separated into two first menu fields (1A, 1B) revealing said underlying layer there between. <IMAGE> <IMAGE> <IMAGE>
