I'm currently working on translating a D10 site based on Layout Builder to other languages. As I want the layouts to be the same in every language, but displaying just a translated version, I don't think that LB Asymmetric Translation contrib module would be an option here.
Quickly I thought of LB Symmetric Translation module, but I realised that it was an alpha version and not updated since 2022. Reading at https://www.drupal.org/project/drupal/issues/2946333 it seems that LB Symmetric is not an option anymore, so...
Does anyone know if there is a stable way to get translated pages, using layout builder + block types, but preserving the layout in different languages?
/admin/structure/block
can be translated, and those blocks can be placed in Layout Builder. However, with that approach, I guess you would have to recreate all your blocks. Paragraphs can also do this, but you would have to recreate all your Layout Builder layouts in paragraphs, which is probably even more work. Another option would be to use content types with fields and then place the fields (not blocks) in Layout Builder. This is what I would do, but it doesn't meet your requirement.
