checkbox-driven page-content filter

[M'karlo webforumsuser@macromedia.com]

I'd like to provide a client-side function to give the user the abiliity to filter a results set, after a search. As an example, a user searches for all restaurants in San Francisco. The results display all restaurants along with a checkbox control enabling the user to show only those restaurants categorized accordingly:

[x] Expensive
[x] Affordable
[x] Cheap

In this case, all restaurants would display, and if the user de-selects Expensive and Affordable, then only the Cheap restaurants would display. I'd like to do that without hitting the server again. I thought this could be done in Javascript, but haven't found an example I could work with. Is this something I can do in DHTML? Can anyone get me closer to a solution?

It would be pretty easy, there are a whole load of different techniques you
could use, either using checkboxes in a form or just plain links. Each
result would have to have a tag included with it, say in an array, and you'd
need a function that when called would show or hide each result based on
that tag... is this making any sense?

Thanks Rob!

Yes, that makes perfect sense, but I need to know HOW to go about doing it. Is this a javascript implementation? If so, are there examples you can point me to?

Yes, you can do it entirely with JavaScript, although you'd need to get your
PHP to write a little more info to the page in the first place to make
things a bit easier (depending on how you do it). I don't know any examples
I'm afraid, it's the kind of thing I usually figure out by myself :)
