How to enable plain text format for body in specific content type I have one content type, where I want to restrict the body field to plain text only. In Drupal 7, there was an option to set the plain text format explicitly in field configuration; however in Drupal 8, there is no "plain text" option in the select box. I cannot change user permissions to text formats, because I want to have plain text for the administrator as well. 

In Drupal 7:



In Drupal 8:

Thanks!
