A system, method, and computer program product for automatically summarizing selections in a hierarchical data tree. Embodiments display a table with at least one entry, corresponding to a level of a branch of a tree, representing a node and comprising a node descriptor, a node selection status indicator, and a summary of selected descendant nodes present. A user may toggle a node selection status via the node selection status indicator, which visually denotes a node selection status is one of selected, unselected, and mixed, according to the number of selected descendant nodes present. The summary of selected descendant nodes comprises a list of descendant node descriptors that summarize an ordered set of nodes between a current node and a lowest level selected node. Either navigation to an entry or modification of a node selection status triggers a propagation of node property updates. |
