Hello @cyberdave and thanks for your reply. You can’t see the issue because is fixed right now. I’ve discovered that it’s a recurring mistake with menus taking the full viewport.
BTW during this days I’ve found several old topic like this where you helped people with the same issue here @cyberdave Help creating full-screen mobile nav - #5 by cyberdave and even you @DFink here How to prevent body from scrolling when modal window open where you’re looking to find out a solution like me. Hope this can be help for others and thanks again both anyway
