The Sliding Menus extension adds a cross-browser sliding transition effect to the menus, with independently controllable open and close animations.
You can use the form below to preview each transition, at a range of resolution and duration values (the values are just examples - in the actual script you can set them precisely).
This extension is not supported in Opera versions earlier than 7.5, Mozilla Gecko browsers earlier than 1.3, Konqueror or Mac/IE5.
