Question

opencart

Good afternoon, who will tell you which way to look in order to implement the output of shoe size options on opencart 2 in this form, https://www.professionalsport.ru/products/adidas-p... with the output of several appropriate sizes. Well and the order of the missing sizes. Thanks

Answer 1

in which direction to look in order to implement the output of shoe size options on opencart 2 in this form

Add another field to the product card for options. It would be possible to get by with a field for the value of the option as a whole, but size matching usually depends on the brand, and sometimes on the model.
There are probably ready-made modules for this.

Answer 2

Maybe someone will be interested, I implemented the size output using htmlspecialchars_decode
