multi-level attributes module

[morditech.com]

Forgive me if this post should be in another category.

I am looking for a module to make multi-level attributes. What I need to do is make new attribute options available when a parent attribute option is selected and only when the parent attribute is selected.

For example:
The customer purchases a shirt. They are presented with an attribute selection of short sleeve or long sleeve. Long sleeve shirts are offered in green and red and the short sleeve shirts are offered in white and blue so depending on the type of shirt there are different colors available.

Does anyone know of a module that will something like this for me?
Thanks in advance.

There's no provision for doing that in MIVA Merchant itself, and I'm not aware of any 3rd party modules that can do that, either. We do have some clients who have implemented something very similar to what you describe, including custom embroidery options, sizes, logowear, etc, but all these stores were built in PHP and use custom written front-end for the shopping cart, while only passing the final selection as a unique product to MIVA Merchant and using that purely for the basket contents tracking and checkout mechanism.

In your example, I'd just make two items (one long, one short sleeve) and use related products to show that the shirt is available as both long and short sleeve.
