All but Hierarchy are similar in the way they operate. For most of the columns, clicking on their header sorts the list by the values in that column (alphabetically or numerically, in ascending order). Clicking the header again reverses the order.
The plus and minus signs ( and
) indicate parent/child relationships for components displayed. The plus symbol associated with a component, or attached to a component type in the
View Usage screen, indicates a parent with child components not currently displayed. Clicking the plus symbol of a parent relationship displays a nested view of the associated child (children).
