lib99 posted the following back in 2009. I can't find where the problem was ever solved. I am looking for exactly the same thing. Can anyone help with that?
Thanks in advance.

"We have a large amount of products within each category. They are each similar, but with slightly different characteristics.

I'm seeking a product selector/filter. Where the end-user can click on the available characteristics to dynamically narrow down the list of products. Haven't yet found the topic in my ZC forum searches.

Example would be Best Buy. [www <dot> bestbuy <dot> com/site/olspage.jsp?id=abcat0101000&type=category] If you're looking for a television, you're presented (left-side) with a number of choices to "narrow" down the product list.

Has anyone attempted this with ZC? I'll probably need to create and program the functionality, but I'm figured I see if there was a foundation out there already. Thanks. "
