Is there a base module that implements the slide in, slide out behaviour like the Admin module? I am looking for a module that implements slide in and slide out on top functionality, similar to the way some websites slide out a contact form when you click the thingy at the side of the page.
 The Admin and Slidebox modules have that ability, but I am looking for some kind of container object that implements the slide in and out functionality.

PS. the tags are not the most accurate but are the nearest.
Superfish is a great option for drop down menus, and you can customise the effects: http://drupal.org/project/superfish

or Nice Menus: http://drupal.org/project/nice_menus

You can also customise the admin menu to add common tasks, by editing the actual links list.
