Abstract

A computer system for supporting a website, comprises a navigation object table defining a number of navigation objects, representing a tree-like navigational structure, and an object handler which uses the table dynamically to construct menus allowing a user to navigate through the navigational structure. Whenever the object handler is called, it is passed a tag identifying an object. It then searches the navigation object table to find objects whose parent object in the tree structure is the object identified by this tag, using these objects to construct the menu. The navigation objects include menu objects specifying subsidiary menus in the tree structure, and selection of one of the menu objects causes a recursive call to the object handler, passing it the tag of the menu object. The system also includes an access control table indicating which users may access which navigation objects, and the object handler uses this access control table to tailor the menus for particular users.
