I have a Wordpress site in my native language and this year I want to add more site languages. Ideally, there would be a switcher button, so after clicking site language will change. And menu with language options would be popup. Here is a good example of it. But this website is probably not built in Wordpress. I like when there is a popup, not just dropdown button in upper menu.
Does anyone know some Wordpress plugin? Or do I need to code it myself?
