Custom fields for participants in Civi are not being presented for addition to Drupal Webform. Event registration is selected and working but the custom field set for participants are not showing up for placement on the webform. Is there a reason that they are not included for webform usage?
Thank you for asking. This should work - and I just double checked and it is working on one of our live projects:
Is it perhaps possible that you've (accidentally) restricted these Custom fields to certain Events only?
