LiveWire is a three-level animated menu system designed for use in a top or bottom navigation frame. The 'first level' consists of menu captions, similar to the standard OS-style menubar. When the mouse moves over a caption, a column of Items slides and fades into view. Moving the mouse over an item causes a row of subitems to appear. LiveWire also contains an optional 'statusbar' area where related messages can be displayed as the mouse moves over menu items.
