Dynamic Relevancy in form fields on Product Detail Pages

Site URL: http://www.nautidoghandmade.com

I sell dog collars... Available in various fabrics and sizes, with different styles and hardware options...

I'd love to have the option to offer dynamically relevant form fields with dependencies on prior form value selections.

For example:

XS is only available as a plastic buckle collar. It is not available in a metal buckle or with an optional martingale limiter.

XL, however, is available in plastic, gold and gun metal. It is available in buckle style, or as a cloth OR chain martingale.

In the current design, if the user selects XS and Gold and Chain Martingale, all that happens is the price *at the top of the page* changes to "unavailable".... This is a terrible user experience because 1) people don't read, and 2) the change happens above the scroll...

The design solve for this relies on using dynamic relevancy and suppression of specific fields based on prior form value selections.

Is there any way to make a feature request for this functionality?

Appreciated!
