Repetitive tasks are error prone. Instead of duplicating effort, duplicate forms and form fields.
To duplicate a form,
Go to Site Administration (your Site’s menu) → Content & Data → Forms.
Click the Actions button () for the form to duplicate.
The form is duplicated and automatically named Copy of [Original Form Name]. Once duplicated, you can edit the form however you want. When you duplicate a form, all configurations and form rules are duplicated as well.
To duplicate a form field,
Go to Site Administration (your Site’s menu) → Content & Data → Forms and open or add a form.
In the Builder view, hover over the form field to duplicate and click the Copy icon ().
The field is duplicated and labeled Copy of [Original Field Label]. All the form’s properties, including its data provider configurations, are copied as well.
