Hi, So I guess What I'm looking for is the ability to have a bunch of simple products grouped into one group product where say, for example, people can check a box for each product they want and then add them all to the basket at once. In this case, each group product would be a "content creator" and each simple product would be various options for that content creator such as a monthly subscription or a single download. Then we would have multiple different content creators on the shopping page. I don't really see a way to do this at the moment unless I could somehow do it by making each content creator a different category. Thanks.
In product brick configuration you can switch input type to checkboxes. This way user will be able to choose multiple products at once. Also in brick configuration you can choose product to display so you can display only products for some particular content creator here. You can add as many product brick to same form as you need - one brick per creator for example. aMember CP -> Configuration -> Forms Editor -> (edit)
