Hi, my variants have the correct id tag for each variant, so each 3 of my buttons are set(Small Medium and Large):




{{product.variants[0].title}}

No matter which size I choose, {{variant.selected}} would still be false for each one. My goal is to make it true when I click on the size so I can add it to cart. How can

Hello there,

To make the {{variant.selected}} variable true when you click on a size, you need to add an event listener to your radio buttons that updates the selected variant when a size is clicked.


  {% for variant in product.variants %}
  
  
  {% endfor %}

In this example, we first loop through all the product variants and generate a radio button for each variant with the correct value and label. Then, we add an event listener to each radio button that updates the {{variant.selected}} variable when clicked.

The event listener finds the selected variant by its ID using the product.variants.find method, and sets the selected property of the variant to true.

Note that you may need to adjust the code to match your specific use case and template.
