hi, I would like to create an online shop that involves electronics. When I have created it I have found the following problems: when I was importing products I couldn't assign them to the correct descriptive feature because in the available descriptive feature there aren't entries like "ram" "motherboard" "processor", and i can't import all images together. Could you tell me if there is any method or form to do it (add new categories). Thank you and goodbye. I am waiting for your feedback.
