I'm at the module where I assigned the menu i want to display and I don´t have that specific option.

Hi R4m1r3zbu3n0,
Looks like you made a mistake here, you buy products on our Joomla Mega Menu, not the "CSS3 Mega Menu", our Joomla Mega Menu has a new version, you can check and update version. And you can send us the site and our account to check your problem, so there is no misunderstanding. Thanks
