Search Box

[tgrk35]

Anyone know how they made that search box pop-up thing on this site?
If you click the down arrow, a box comes up with a search input in it.

I would like to do this on my site somehow. Anyone know how it's done?

Some JavaScript is responsible for the visible portion of that, and PHP is responsible for the actual searching.

Any idea on a script or THE script they used for this?

Thanks :)
