Problem: The client is implementing WPML with Advanced Custom Fields (ACF) Multilingual and seeks confirmation on best practices for field translation settings, ensuring layout elements sync across languages, and maintaining a scalable multilingual structure. Solution: We recommend setting ACF Field Groups to 'Not translatable' and choosing the appropriate translation preferences for fields: use 'Copy' for layout/structure fields (like repeaters, icons, CTAs) to maintain synchronization across languages, and 'Translate' for user-facing text fields to allow proper content translation. It's important not to manage ACF fields from the WPML → Settings → Custom Fields Translation screen but directly from the ACF Field Group edit screen. The fields listed there, including dynamically created ones, are normal for ACF-based sites and should remain as configured without manual adjustments. For detailed guidelines, refer to ACF Field Groups translation settings and recommended custom fields translation preferences for ACF and WPML.
