Opencart unit how to add?

Question

opencart

Good afternoon! There is a task to add a unit of measure for the product next to the price. I tried to modify the unit of change myself by using the empty 'jan' field, in all controllers I added this field to the products array. Everything started to work well, except for the modules bestsellers, latest, etc., although they have the same structure. Maybe someone faced such a problem in the development process? Here is the site .

Answer 1

What do you mean by "self-improvement"? Do you want to enter data in the "jan" field and then display it on the product card?
