choose lang default in custom page

Nath,

Cookie is the best solution that works to do this, save select lang cookie and use that cookie value in your custom page.

Or you can use the api to get prefer language setting by user in their profile.

<#assign user_language = settings.name.get("profile.language", "en")!"en"/>

Falls back to English if it doesn't find anything. Obviously you can change that default to any other language your community supports.

how i can write and read cookie with Freemarker ? i would like save select lang in page initialization config

Thanks for your help
