I am creating a theme for a website that has products. So I created a custom post type called products for all the information needed.
I need a way to allow the client to add headings and under those headings a list of product codes.
I know from front-end it can be done in many ways but in the back end of the database I need the best way for them to add up to 8 headings and as many product codes as they need.
Not sure of the best solution for this. Any ideas?
