A method and system are described providing for the compact navigation of a tree structure. According to an exemplary embodiment, a path in the tree structure is displayed. A selection component is included in the displayed path to represent a level of the tree structure at which there exists a plurality of nodes. A selection of a node from among the nodes existing at the level of the tree structure represented by the selection component is allowed when the selection component has focus. Only a selected node is displayed when the selection component does not have focus. The method and system allow complex hierarchical data structures to be presented in a compact form appropriate for portable electronic devices having smaller-sized displays.
