Dear Raffaele,
What is the exactly the problem with your here?! The menu does not show in other languages?
If Yes, please check my above screenshot! You must assign template to your language you want to display menu!
I've helped you assign some templates, and you see menu showing in Italian, Spanish, you must do the same for other language by yourself!
PS: Please enable Copyright Text or purchase Template Copyright Removal feature. If not, we will close topic and remove your account!
Best regards.
