What is the best solution for filling a portuguese postal code? A mask input, or separate input fields?
The format for the portuguese postal code is [xxxx]-[xxx] So what is best?
Input Mask [xxxx-xxx] - The hyphen is there already, giving the help for the user.
Separate Input Fields [xxxx]-[xxx] - This is not very good to form validation, but its easier for users i think.
What do you think? Thanks
