So, replicating the template for each language was the recommended course of actions. My question was whether there is another way to do this without having a different template for each language. The link would have helped if I didn't already figure it out. Thanks, anyway.
By the way, I find out if you do not select Megamenu in the template settings you can use one template with different menu for each language. This works fine especially if you use the offcanvas menu for things that do not require translation like external links.
