My customer asks to make the existing application multilingual, which I’m currently successfully implementing. Your documentation is getting better, Cuba Team 
I have a few screens that use the Filter or Webfilter component and I’d like to implement multiple languages here too.
What would be the approach to accomplish that? I tried to extend the filter-edit.xml:filterEditor but I get an error Legacy screen can only be extended with other Legacy screen
Hi,
CUBA supports localizations of all built-in messages. You don’t need to extend Filter component to translate its captions to another languages.
There are already several localizations available, see “Localization” addons in the Marketplace:
If the language you need isn’t supported yet, you’ll need to create new localization and translate localization strings from the platform and all addons your project uses. Information is available here: GitHub - cuba-platform/translations: Translations for the CUBA Platform screens and UI components
Thanks, that’s very helpful, although the language i need (Japanese) is not available.
I think the only translation I need is for the filter component. Everything else provided by the platform can remain in English.
