Título: Tag autocomplete should suggest only prefix matches, not partial matches

When adding tags to a product in the Shopify admin, the autocomplete suggests any tag that contains the typed text anywhere in the tag name. This causes accidental tag additions when similar tags exist in the store.

For example, typing “4000” suggests both “compat-john-deere-4000” and “compat-ford-new-holland-4000”, making it easy to select the wrong tag by mistake.

The autocomplete should only suggest tags that start with the typed text (prefix match), not tags that contain it anywhere. This would prevent accidental tag errors and improve accuracy when managing large tag libraries.

Hey @oleoclick.pt

It’s a real UX annoyance, I know because adding tags previously used to be so easy and quick. One more thing, posting it here won’t reach the product team, this board is mostly merchants, so drop it on community.shopify.dev where Shopify staff actually engage if you want it considered.

Also, for applying tags across a big catalog accurately, it’s also worth doing it through CSV import or the bulk editor where you paste the exact tag text, since there’s no dropdown to mis-click there at all. Hope that helps.

Best,
