I'm trying to find the functionality of the variation selection in a single product:
Does anyone know in what wocommerce php file this functionality is located? Or how can I search for it?
Thanks
The JS file is located at /wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.js. That lists all the functionality that is encapsulated within the VariationForm class/object.
