Editable field which does not get saved in document when saved

Ever wondered whether an editable field can be created on a form which does not get saved when the document is saved! Well it can be done. It’s pretty simple. All you need to do is to write @DeleteField in the "Input Translation" formula of the editable field in the form.

You can have an elaborate formula written in Input Translation based on which you can decide whether to save the field in document or not.
