Hi, I invite you to reread what I've explained carefully.
You're showing me how to manage a multilingual site by creating (in my case, we're talking about 4 languages) a collection for each language.
That's the simple part; it obviously works.
However, I've explained a different problem.
And I've given the example of a real estate site.
If my collection has fields that aren't translated, following your instructions, I still have to create these fields 4 times, one for each language, and that's the wrong procedure.
For example, consider the photo gallery: I have 15 images for each property. If I have to create 4 collections, I have to repeat the image insertion process 4 times, when there can only be one gallery field.
I've solved the problem so far by using Regular Labs' Conditional Content, which allows me to read based on the browser's content, without hiding any text in the code that would penalize my SEO.
Perhaps an alternative would be to create a separate collection for galleries (and all those parts of the property that don't change, but there are many), but this would require me to create too many reports because I would have to repeat the property in each dedicated collection, and then associate them with each other.
What I'm asking is for a solution where the language can be directly associated with the field.
In your book example, as you can see, you have several fields, but they're all associated with the same language.
Imagine you need to insert the cover or multiple images of the same book. You'd have to repeat the gallery for each language, and this would apply to all fields, which are the same regardless of language.
I hope I've explained the problem you're encountering better.
