Pop-Up menu is a DHTML-driven navigational system that allows Webmasters to add Windows-like menus to their Web pages. New features include several bug fixes for the menu and the menu creator, the option to snap the menu at the browser window edges, and the ability to configure the menu to animate the opening of the sub-menus.
Limitations in this version include predefined color styles and the inability to save pop-up menus for later editing.
