Hierarchical navigation control

Abstract:

A user interaction is detected, selecting a unit with a user input mechanism. A unit hierarchy path that is used to categorize units, is accessed and a node in the unit hierarchy path, corresponding to the selected unit, is identified. A set of ancestor nodes in the unit hierarchy path is also identified, and a user interface breadcrumb control is generated based upon the selected unit and the identified ancestor nodes. A display system is controlled to render a display page for the selected unit, along with the breadcrumb control.
