Abstract: The objective of the instant invention is to define a computer user interface display system that presents hierarchical data in an enhanced tree presentation control that blends the ease-of-use character of the familiar "tree presentation control" with a technique for navigating more complex lattice data structures, while at the same time providing more node information by displaying configured lattice-node labels along with the node's name. Thus a primary objective of this invention is to facilitate building, maintaining and using a multiple inheritance taxonomy such as a product catalog data base by means of a multi-navigation path browsing system, which is made possible through the capability of this system's multiple inheritance capability; with indicators in the tree view to indicate ancestors such as immediate parents and further removed ancestors.
