How are these Attributes laid out?

I've been asking for help with this within another thread that has been on-going, but I don't think anyone is seeing it any longer - hence this thread.

One product on my client's site: http://www.officemasterchairs.net/index.php?main_page=product_info&cPath=1&products_id=1 ... nearly all the chairs have a similar amount of fabric choices. Some also have the addition choice of chair arms.

My client agrees that the list of fabrics is daunting and saw another way to tightening it up. The solution is actually on another Zencart site that is also a rep for the same vendor, and thus the same fabric choices.

What addon/modification are they using?
Here is one chair as an example ... she loves how the attributes are displayed and wants that.

I could really use some help in identifying the addon used to create the attributes layout like that. It's so nice and tight. I have emailed the webmaster, but never received a response.

That site does not appear to be a ZenCart site - or one where credit has been removed and old
Using tables for design

If it's Zen Cart, it is a truly ancient version. My guess is osCommerce with a Template Monster template. The attribute handling appears to be custom-written javascript, and I highly doubt they will give or sell trade-specific software to any competitor even if it would work for you.

Well, fudge. Thanks for looking into that.

I wish I was more proficient with PHP and java to be able to do something similar.

If anyone can suggest something to help tighten up the many attributes, that would be great. Especially since I'm getting another e-commerce client whose products will also have quite a laundry list of attributes - so it would be nice to be able to fix this.

It doesn't affect the operation of attributes in any way, but Flexible Attributes from Plugins can help you massage the layout of your attributes if that is of any use.
