Building reliable bilingual forms for LTR and RTL layouts

1 min read
A practical implementation note on validation, select controls, required fields, and consistent form behaviour across English and Arabic layouts.
Bilingual form interface with validation controls

Bilingual forms require more than translating labels. Direction, native controls, validation, spacing, and focus behaviour all need to remain predictable in both LTR and RTL layouts.

What we changed

  • Kept server-side validation as the source of truth.
  • Disabled submission until required client-side fields are complete.
  • Used direction-aware spacing for select controls.
  • Associated errors with their fields and groups.
  • Tested invalid and live submissions through the Next.js and WordPress flow.

What we learned

Small inconsistencies become obvious when the same form is viewed in two directions and two themes. A shared component and a repeatable test route are more reliable than one-off CSS fixes.
