NESTED ROADMAP NAVIGATION IN A GRAPHICAL USER INTERFACE

摘要

Systems and methods for nested roadmap information navigation in a graphical user interface (GUI) where a sequence of items is generated and stored in a memory of a computer system. The sequence of items includes at least one compound item. A number of user interface (UI) elements are displayed in a GUI screen, wherein each UI element represents an item of the sequence of items, and wherein the UI elements are ordered according to the sequence of items. The displayed UI elements include a UI element representing a compound item of the sequence of items. The compound item could be selected as a currently active item. The UI element representing the selected compound item can gradually expand to display one or more new UI elements representing component items subordinate to the compound item. The first of the component items is automatically selected as a currently active item.
