So for this site I'm building I need to be able to do the following.
- When user views the site in English show all English articles
- When the user views the site in Dutch, show all Dutch articles - but also the untranslated English ones
- When the user views the site in German, show all German articles - but also the untranslated English ones.
The contextual filter, 'Content translation: Language' only allows to put in one value. That is either a language specified, or all.
But in my case it would be required to be able to set for instance "en+nl" or "en+de". Like one can do with taxonomy 'Has Taxonomy', I would like something like 'Has Language'.
