Users can add additional fields on the customer page, transaction page, and pay page.
For all fields there are three options:
Required: When the required checkbox is checked, the user field becomes mandatory. The account will not be saved or the transaction will not be processed until filled.
Editable: If an editable checkbox is selected, the field will become editable, i.e., the user can edit the user field.
If not editable, then the default value should be provided for that field. The default value will be populated for the user field and will not be editable.
