Not sure how this works exactly. Can you please explain?

So the rest of the configuration stays the same, the only factor changing is how it's displayed? Thanks for explaining, I am just curious because I want to implement it to my site.

yes, assuming all your language versions have the same structure, you will always see all available languages (besides the current one) and on change of language you stay on the same page. works great on my site https://erz.lu

no further config changes required.

Oh, sweet. Your site looks great by the way. I really like the site you posted earlier too, I hope this gets approved; I was thinking of doing the research and adding a similar PR myself. Thanks!

Edit: p.s. -- i added it to my website (which is still wip btw). thanks!

What happens if there no translation for a specific page? Will it redirect to a 404 page?

[luizdepra]

Ok, forget it. The lang selector does not display on pages without translations.

Thank you.

Closes #293.
