A method of displaying and navigating information using a hierarchical, spring loaded DHTML menu system that adjusts to fit the boundaries of a resizable, container (FIG. 1). A set of standard HTML table row elements, having a hierachical dependency (11), is consistently displayed as a web-page, under reasonable resizing. This is done using a strut row that produces the largest width requirement when the table structure is resizing to occupy a small width. Only the current row elements and the strut element are required in calculating table resizing to ensure that whichever data elements are displayed when a web-page resizing occurs, the browser auto-layout algorithm calculations will result in a resize attributes that enables all other row elements of that menu to be accommodated by the newly determined table width. As the row elements may themselves be table structures, nested menus of information may be displayed and navigated (12).
