Might you please help indicating how to set eCommerce "optional products" as required in cart as a user is buying main product?
I mean: Main product is current product user is browsing, optional products are those being added to main product.
Is this possible?
On website module configuration-settings-tick optional products in customer experience.Then go to website module and select products.you can see published products there.So edit a product and select sales from it.There you can set optional products of that main product by adding optional products to optional product field under website.
Then visit website and shop and add that product to the cart.Then a pop up window will appear to add that optional products and proceed checkout.
