Variant picker on collection page not updating price - Tinker

Store Design
1

Having issues with the Variant Picker on collection pages not loading the corresponding variant price, or eventually loading once clicking back and forth on different variants a few times.

Seems to be working correctly on the product page. Using Tinker theme.

Hey @HBaars

The issue with the variant price not updating on the collection page is due to missing product data and JS logic. I’ve prepared a quick fix using product JSON and a script to update the price when a variant is selected.


  

  

    {{ product.price | money }}

JavaScript Code (add to your theme’s main JS file):

document.addEventListener('DOMContentLoaded', function () {
  document.querySelectorAll('.product-card').forEach(card => {
    const productData = JSON.parse(card.dataset.product);
    const variantSelector = card.querySelector('.variant-picker');
    const priceContainer = card.querySelector('.price');

    if (variantSelector && priceContainer) {
      variantSelector.addEventListener('change', (e) => {
        const selectedId = e.target.value;
        const selectedVariant = productData.variants.find(v => v.id == selectedId);

        if (selectedVariant) {
          priceContainer.innerHTML = Shopify.formatMoney(
            selectedVariant.price,
            "{{ shop.money_format }}"
          );
        }
      });
    }
  });
});

Let me know if you’d like me to implement this directly for you — please feel free to reach out!

Hi @HBaars ,

What version of the Tinker theme are you using?

It does this automatically on version 1.0.5 without code changes so you may need to update.

Hope that helps,
Jake

Ended up moving from Tinker 1.0.2 to 1.0.5 to resolve this issue.
