content filtering by atribute (tartan finder)

My client sells kilts, one of the atributes for these is the type of tartan used to make the kilts. In order for the customers to know which tartan they would like, they may like to browse them using what I would call a 'tartan finder'. The shopping cart I would like to use is the interspire profesional shopping cart so this all needs to be incorporated into this. 1. Tartans each have an image and are sorted by group name then defined again by indivual name of tartan. ie Campbel Tartans > Modern Campbell or Traditional Campbell 2. I need the customer to be able to select a tartan they would like thier kilt to be made in by either, browsing the tartan finder or just by simply selcting it from a drop down option on checkout...just as they would for example if they wanted a red blue or green t shirt. I would like a image to remain as to what tartan has been selected and all this information to be carried forward through the entire checkout process. Note The tartans are not products so people dont have the option to buy tartans they can only buy kilts or other products which are made from specific tartans. 3. Not all products are made from all different tartans so this has to be able to be controled in the control panel and followed through to the customer front end 4. All of the above needs to be managed by my client via the admin interface. ie add/delete tartans link what kilts are available in specific tartans An example of how this might look but not exact has been shown to me at [login to view URL] select tartan and fabic finder - please note how this website deals with the tartan selection near the end of the checkout process Please also note this is a live website and has nothing to do with me I am just pointing you to this website for illustration purposes. Thanks in advance
