Theme Fields Added Constraints and Fallback Images

Editors need reliable defaults before they can manage a live theme without breaking pages. Theme fields now support number and text constraints, select options load more reliably, relationship-backed attributes resolve more safely, and fallback images work when content is incomplete.

Launch-readiness features

These are launch-readiness features rather than experimental additions. Editors need reliable defaults, bounded inputs, and safe relationship resolution before they can be trusted to manage a live theme without breaking pages.

What changed

Number fields can now have minimum and maximum values. Text fields can have length constraints. Fallback images display correctly when the expected image field is empty. Select options load reliably in all field contexts.
