Change menu when langage changes

What menu do you mean?

My guess would be the navigation menu ??

I’ve been trying to figure that out too.

I found that when using categories for the menu, the menu adapts automatically to the language.

But how do you set pages as a menu item and make them appear automatically for each language version?

Head over your custom menu, click on the menu items and you will find checkboxes that will help you decide where you want to display them. here’s a screenshot: https://i.snag.gy/YAxTQP.jpg
