How to make a drop down search box like Vbulletin

Hello,
I am looking for a javascript that will allow me to make a drop down search box like vbulletin does.

If you go to this link: http://www.vbulletin.com/forum/ And click on search you will see exactly what I would like to do.


Thanks for any help with this.
