We are building a Shopify store using the New Standard theme, to sell eyeglass frames.
With our concept , when a client choose a frame, he then needs to choose some colour inserts to fit in the frame (choice of over 200 inserts). We need a selection tool for these inserts, visible in each product page, so whatever frame is selected, the inserts are always visible and can be selected and added to the shopping cart.
Please visit [url removed, login to view] to see the concept. We see something similar to the selection wheel on this site, but are open to other options.
