I have simple example to explain my question.
- I have linked two tables with a multi-select field: Books and Authors.
- For every Authors I can select many Books that the Author has wrote. And for every Book I can select many Authors that have wrote that book.
- A Book is wrote in a language and the Authors know only one language
Question: how to filter the select-list with only those Authors that use the language of the Book if I want to associate correctly the Authors with the Books based on the language?
Thank you in advance for your help
