Sorry for not responding here soon Martin. Been trying to come up with a way to do that, but SimpleCart is pretty set on the category > product relation. You can do nested categories but no nested products that I can come up with.
Commerce will let you manage your catalog any way you want to, even by using other extras like SimpleCart or MiniShop - or a custom database table! That’s one of the key areas we’ll talk about while getting ready for the release
No problem - as I wrote above, I solved this by using a TV which holds the IDs of the “child” resources.
Can’t wait for Commerce - the suspense is killing me!
