Does Opigno support creation of Activities that are Webform or Content? I searched/read docs, but can't find anything. Seems I can create new Activity Types, then New Activities, but I keep running into display issues (some are Drupal, some user error, but I have a feeling some are Opigno restrictions). Any input or learning source would be most welcome. Thank you.
Yes it's definitely possible
Yes it's definitely possible to do it.
But we don't have any documentation about it right now. You should investigate how the existing activities are built (for example the long answer question).
