<p><P>PROBLEM TO BE SOLVED: To provide hierarchical menus which overcome various inconvenient points of the conventional hierarchical menus. <P>SOLUTION: A hierarchical menu system displays submenus in place of parent menus when appropriate menu items are selected from parent menus and submenus and vice versa. Parent menu items selected from parent menus are displayed within submenus as links back to previous parent menus. Benefits of the disclosed hierarchical menu system include the ability to implement a hierarchical menu on devices having varying screen sizes, including small-screen devices, while maintaining a history of previously selected menu items that enable a user to navigate within the hierarchical menu to any previously displayed menu. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
