Main issue guide: Duplicate IDs

At a glance

Instructional

Stable, unique identifiers

Duplicate IDs and broken ARIA relationships confuse assistive tech when it resolves references.

Where this comes from on Shopify

Theme Liquid, JSON templates, and app embeds. Coordinate with the theme or app vendor when markup is not yours.

What this issue means

Fix

Rename duplicates; generate stable unique ids for lists rendered in loops.

How to fix on Shopify

In Shopify, prioritize theme Liquid and section JSON: product cards, cart drawers, and app embeds. Some issues need a theme developer or app vendor; capture the public report link when you open a ticket.

How to fix

Ensure ids are unique per document; generate stable unique ids in lists.

Fix templates so duplicated components do not reuse hard-coded ids.

Common mistakes on Shopify

  • Editing checkout (limited) vs theme—know which surface you can change.
  • Forgetting to test accelerated/mobile themes.

How to verify the fix

  1. Preview the theme or use a development theme URL the scanner can reach.
  2. Test cart and collection templates if that is where the issue appeared.
  3. Rerun the scan after theme deploy; keep before/after report URLs.
