See example of initial vendor fields configuration in: app/code/community/Unirgy/Dropship/etc/config.xml

Create a new config file or use your custom module's config.xml

For a standalone customization, can use app/etc/modules/z_custom_fields.xml:

z_custom_fields.xml

• Field Notes:
  • Fields will be taken automatically from vendor object and serialized into db vendor metafield.
  • If you want to save them in a separate field table, create field with this name in udropship_vendor.
  • It is prudent to use a prefix for field names to avoid conflict with existing fields
• Possible field types:
  • text (default)
  • password
  • textarea
  • select
  • multiselect
  • image
  • date
  • datetime
• If no <source_model> is specified, app/code/community/Unirgy/Dropship/Model/Source.php class will be used.
  • You can create your own combined dropdown source classes by extending this class and overriding toOptionHash() method.
