Slide-down/drop-down effect - like google?

Hi:

has anyone every seen Google’s main search page where they have some
type of javascript

control tied to a link called “more” at the end of their row of links to
other stuff? Does

rails have some type of implementation of a control like that or does
someone know where I

can get something like that? The control actually overlays ontop of the
page, and is really

nice!

Thanks very much in advance!

Both have good effect frameworks. There are others of course but these
seem
to be the most popular right now.
