I am new to presta shop. Tried to search trough the forum and docs but no replies. I want to solve following scenario. I have pants with color and and size ( let's say black and navy, with S, M each ). Each combination has a code so Black-S is code 197197 BLack M is code 197198 and so on. I have jackets with color and and size ( let's say black and navy, with S, M each ). Coding same as above. I wish to sell them separately and together in a "suit" product. Suit product should help combine M black pants + M black jacket f.e. , L black pants + L black jacket f.e. and so on . Separately no problem, also with stock control. Together I wasn't able to image how I could configure a suit product. Any help would be highly appreciated. Thank you
