i've got a question: if i publish n modules into the top-a position, if there a setting to say to the template to show them in max 4 per row? Same question for the top-b-c-d positions. I've tried to put 6 modules into the top-a and all stay on the same row. thanks for any help.

You can change the row in the template options > Module

thanks for the reply. I sed the top-a as parallel but if i publish in there more the 4 module they where published all inline. I would like to know if there is a way that from the 5th module in the same position it could be visible on the next line (without using the top-b). www.sebg.it/bg/index.php/edilforum
