How to add Infinite Options selectors to your product page
Since the Infinite Options bundle type doesn't utilize Shopify's native variants, you'll need to add the option selector to your product pages manually.
You can follow this guide to get set up.
Here’s an extra tip: If you have quick add-to-cart buttons on your collection pages, they might override the bundle product page and won't show the drop-down selectors to users. In that case, follow this guide to adjust the quick add button behavior so it redirects to the bundle product page: Quick View or Quick Add to Cart Outside Product Page (Infinite Options Bundle).
