Hello to the Dataease team! 

I have a question: Is there a way to copy a subform from an existing form to another form? Like the normal fields ?
For example, if you want to create a copy of a form, but not 1:1.
This can sometimes be necessary if the form is damaged by an OML crash. 
Thank you in advance and best regards

No. You can't copy an entire Subform. You can copy the content of a subform from one form to another, but not the entire subform with all the columns etc.
