I want to increase quantity in increments of 3 on Product pages, in My debut theme

I have used this code in my section Product- template.liquid
{{ ‘products.product.quantity’ | t }}

It is working fine, But if i enter Quantiy as manual as 4 it is also adding to cart, i need to restrict this in js, My exact requirment is only multiples of 3 should be added, if i enter manually any number that is not part of multiples of 3 it should display errror message. can you help me to fix this

Hello @muthukumar ,

Please share:

  • your store URL;
  • page URL with the issue you mention;
  • storefront password (if your store has one).

If the store is not online yet, please follow this quick tutorial to learn how to safely and temporarily share an offline/unpublished theme URL.

Kind regards,
Diego
