Sometimes you have a content types that has a large number of fields. When the user is filling out the fields they might have to stop at points to gather more content or take a short break. Unfortunately Drupal will not let you save the content type unless it is valid.
I found a tutorial which describes the creation of such a module, but it's for Drupal 7.
Please make this module compatible for Drupal 8.
