The Add product to cart action adds an item to the currently active cart. You can configure the action in one of two ways:
Add active product to cart
Adds the product that was selected earlier from a list or grid.
Add a specific SKU to cart
Adds a fixed product using its SKU. Enter the SKU manually in the field provided.
This action is typically linked to elements in two ways. You can:
Link it directly to a repeater div inside a product list or grid, so products are added to the cart immediately when selected (ideal for simple, non-variable products)
Attach it to a button inside a product details pop-up, so the product is added after reviewing more information and selecting a variant.
