摘要

The method involves selecting a set of classification elements, and attributes associated with the set of classification elements. A navigation tree is calculated from a set of objects selected by a user and from a strategy from a menu zone (Z7) so as to order a set of levels of the navigation tree. A set of nodes associated with a level and a value of the attributes is displayed on a screen of a terminal. A set of navigation controls is executed to select one node in the tree and to display information associated with the selected node.
