Adding multiple variations to Opencart cart?

Question

opencart

Good afternoon, there is a task so that several items of the same product can be added to the basket, but with different values ​​​​(for example, size XS and S). I understand that this can be done through checkboxes. But the checkbox adds all selected options as one position.
I couldn't find a solution on Google, maybe I'm looking in the wrong place.
I would be grateful for any information on the topic)

Answer 1

You need to rewrite the add to cart script.
It is usually located in the product card template, well, or in the script file from the template.
