I need to make several choices available i.e. create child products of child products, or somehow else that customers can make a second choice based on their first choice and a third choice based on their second choice.
I can create child products of child products, but the second "layer" products are not displayed. What do I ned to do or what am I doing wrong?
(I am relatively new to this, far from an Expert)
You can use for this the dynamical childs and you would see one dropdown, use it,.. .get two dropdowns, use the seconend and so on.
but easier is the Multivariant. Check the demo http://demo.virtuemart.net/default-products/vm-t-shirt-multi-variant-detail
