How to create custom shipping module
When creating a submodule for shipping I have to add some additional fields would like to hide some fields.
Lets say I do offer shipping whrere I would like to ask only phone number and one custom value.
Wich way should I go.
1.Should I use costom fields under shipping services pane?
2. Should I do something with shipping information fields?
I would prefere the second one but becouse then maybe I could save stuff much easier way into order fields (As far as I see :D).
Still should I make new address plugin or could I just say show some fields if something is selected.
