Can I add an element to a form that is already receiving submissions?

I need to add a selection to a category

Can I do that?

Will it mess up forms already submitted?

Hi, thank you for contacting us.

Please note that adding elements to the form should in general be okay and won't corrupt the submissions you already have. It is the removal of fields that can affect those submissions.

I hope this helps. If you need further assistance please let us know. Thank you.
