How do we set required for new & optional for existing fields - when adding basic field to content type?
When using Drupal 8 following this how to article shows the steps to take to add a basic field to content types. https://www.drupal.org/docs/user_guide/en/structure-fields.html
What I want to learn how to accomplish is to make the new field "Required" for all newly created content types however for existing content I want the field to be optional.
Any & all feedback is greatly appreciated.
