Im not speaking nor reading deutch at all, maybe what i m asking is already written somewhere

Is there a way to have a different layout for the category page, and the product details page ?
at the moment, both modules (product overview and singleview) are on the same page or layout, it means, if you have the left column on the cateogry page, you 'll also have it on the product detail page.
It would be so nice that this e-commerce module could respect the contao "how to" like news or events things.
Thanks in advance for answer

Regards
