Dawn Theme / Add To Cart Button Doesn't Work On Products With Variants

Technical Q&A

Topic summary

Add to Cart button in Shopify’s Dawn theme fails on products with variants: only the first variant can be added, and selecting any other variant disables (grays out) the button.

A previously suggested fix from a linked community thread was tried but did not resolve the issue. Recent theme customizations by Shopify Experts may be influencing the behavior.

A helper asked for the store URL to inspect the site directly; no technical diagnosis or code review has been provided yet.

Key terms:

  • Variant: a specific product option combination (e.g., size/color).

Current status:

  • No resolution; the issue remains open.

Action items:

  • Provide the store URL for troubleshooting.
  • Engage the Shopify Experts who performed the customizations to review potential conflicts in theme scripts or variant selection logic.

I am experiencing the same issue described here, but the solution given didn’t work for me.

https://community.shopify.com/topic/1590659

Customers can only add the first variant to cart. If they choose another variant, the “add to cart” button turns gray and doesn’t work.

I have had customizations recently by Shopify Experts and am trying to get them to address. Any ideas or help is appreciated.

Hi @OrangeCart

You should share your store url, otherwise I can’t take a look at your store :slightly_smiling_face:
