I want to create my own Product Field.
one finds all the classes for the Product Field. How do I get further with this?
Is there an example somewhere that shows which of the classes-files for the pricing product are necessary?
How can I include them - or let’s say, “put them together” - to make my own product field work?
IN OTHER WORDS: Can I just copy these files and rename the classes? And then continue from there (by extending the functionality)?
