AniMenu by Cool Focus

AniMenu is a 2-level vertical menu. First-level items can act as links or can contain a panel of second-level items. The second level is revealed either by clicking the caption or hovering over it: items below slide upward or downward. If you choose 'hover' mode, the hover-delay time can be set in milliseconds. AniMenu can also be used in 'text-sensitive' mode, looking and behaving like HTML links. Captions and items can use gradient fills.
