Custom Item Fields now translate into every menu language
If you run your storefront in more than one language, your Custom Item Fields — the merchant-defined extra fields per item (size, vehicle make, service type, special instructions) — now translate alongside everything else customers see.
In the Fields Editor. Open any item, click Open Fields Editor, and you'll see a row of language tabs above the field list — one per menu language you've enabled. Click a tab to switch which language slot every input reads from and writes into. Type the translated label, placeholder, and select-option values; switch back to confirm. Your previous-language values are preserved when you switch tabs.
Single-language stores see the editor exactly as before — no language tabs appear.
AI auto-translate covers them too. When you tick AI auto-translate to other menu languages on item save, the AI now fans the custom-field titles, placeholders, and select options out into every enabled menu language alongside the item's name, summary, description, variant group names, and add-on names. Same credit cost as the other translatable fields. Hand-edited translations are preserved unless you also tick Force translate all.
Existing fields keep working. Whatever language you'd typed your custom fields in before now lives in that language's slot — customers in other languages see your original text until you (or AI auto-translate) fill in their language. No customer-facing breakage; the storefront resolves to whichever language is configured.
What's not in scope (yet). Order-level custom fields configured under Settings > Checkout > Custom Fields stay single-language for now — that surface uses a separate editor and ships in its own slice. The per-item custom fields covered here are the ones on the Custom Fields card on each item's edit page.
