Hi @renar
I’m not so sure how the saving process in Gravity Form and WPML works, so I’m sorry if I can’t help you much. For something like that, I suggest you consult to their support instead. After you know how to create the translated post using those plugins, then you need to get the translated post ID. By using this ID, you can add the values to the translated post by using the update_field() function.
I hope this makes sense 🙂
