System and method for implementing selectively index enabled multi-column lists in a computer system

Abstract

System and method for implementing selectively index enabled multi-column lists in a graphical user interface for a computer system. The graphical user interface contains a table of entries organized by columns. The columns are displayed vertically adjacent to one another. A user selectable vertical line (the divider line) can be moved from an extreme left column position to a position between adjacent columns. When a column is between the divider line and the extreme left column position, the column becomes index enabled. A single column (e.g., the left most column) or multiple columns can be index enabled simultaneously. A column can be positioned between the divider line and the extreme left column position by column reordering, e.g., leaving the divider line in a fixed position and dragging and dropping the column from a position right of the divider line. By making a column index enabled, an index of the items of the column is made and when indexed, every unique column item is represented only once in the column by an index item. A user selectable two position representation (e.g., a triangle, arrow, etc.) can be used to open (expand) or close the index item. When closed, all information contained within the index item is collapsed in the user interface. When expanded, this information can be displayed in the user interface. The present invention advantageously provides advantages of tree-views (e.g., the ease of searching through data in a hierarchical format) while also offering advantages of multi-column list displays (e.g., volume of information presentation).
