Hi Daniele
in the latest version, when i hover the mouse in the mega menu area (not the link), it opens automatically, plz watch the video:
I think its something related to proform nestable, because when i delete it, works almost fine😅
Can you share a link? I really don’t know what the Pro Forms have to do with the Bricks Mega Menu. There is no connection 
A link would be helpful. Thanks!
Well its the transition for the submit button cause problem 
i fixed it. Thanks
