If the map contains a multi-element legend, the entries of that legend appear as the fifth level in the hierarchy. Information that is available in the Information Window for any map is listed the Component Index at this site. Text searches are supported through the Search Box. The order in which layers are first selected determines the order in which they are stacked in the view window, regardless of whether they are deselected later in the same web session. The hierarchical structure of the web server, inherited from the IMS, permits the user to mix map features from deep levels within any category.
Deselected maps remain in their original position in the stack but become invisible.
Selecting those maps again in the session does not move them.
