Multiple choice search in Wordpress

does any one know how开发者_开发问答 to createa search panel similar to the "quick find" bar on this site?

I've been trying to find a plugin or tutorial but have had no luck at all. I'm looking for some thing that filters child categories according the the parent category the user has clicked on.

Please could some one point me in the right direction.

Thanks very much

Danny

Look at the page source; that's not a Wordpress site, though you can see some of the Javascript involved with the search bar. Have you searched for plugins? WordPress › WordPress Plugins or asked in the WordPRess forums? There are ways to implement a search like that in WordPress.
