Follow the steps below to delete a field or group in your base model.
NOTE: A repeating group can only be deleted if it has no repeating fields within it. All associated fields must be deleted before the parent group can be deleted.
Open the Base Model configuration (Administration > Applications > App Designer > Base Model):
Select an existing field (can be non-repeating or part of a field group), then click Delete. The Delete Confirmation screen appears:
Click Yes to delete the field or No to cancel.
After clicking Yes, the Configure fields for Application screen appears, with the deleted field removed.
