How to Prevent Size Chart App Conflicts on Shopify
DOM fights. Stack overflow. Duplicate buttons. Here's how to fix.
Common Conflicts
Duplicate buttons. Two size chart apps both inject buttons. Solution: uninstall one. Don't run two same-purpose apps.
z-index wars. Modal stacks below another app's modal. Solution: bump z-index, or use Shadow DOM.
jQuery version conflicts. One app loads jQuery 1.x, another 3.x. Tailor Size Guide uses zero jQuery, no conflict possible.
CSS bleed. Theme app CSS overrides your size chart styles. Solution: use Shadow DOM or scoped CSS.
Debug Steps
1. Open product page in dev tools. Console: any errors?
2. Disable apps one by one. Conflict goes away → that's the culprit.
3. Contact app vendor with the conflict details — most fix promptly.
4. If unresolvable, swap to a conflict-aware app like Tailor Size Guide.
