I'm using Drupal, CiviCRM, CiviCRM Entity and Webform CiviCRM.
My hope is to link an "activity" (described on a Drupal node) to a group ("Sign up for news about this activity").
So the Group Id would be stored in a field on the Drupal node, and when I click "Sign up" I'm taken to a form where I can sign up to that group.
Is there a way of doing that with Webform CiviCRM?
I've tried setting "Enable Tags and Groups Fields" to "Yes" but I can't see how to pass in the Group Id.
