Cognito Forms does not currently support the ability to copy sections (or groups of fields) between forms, or merge two forms together. Alternatively, we recommend making a copy of your form and removing or adding fields as necessary.
To create a copy of your form:
In your Cognito Forms account, open your organization’s Dashboard.
Select the form title, and then select the Copy option.
Edit the title, and select the organization and/or folder where you want to copy the form. If your form is not encrypted, optionally include the associated entry data.
Hit the Copy button to automatically save your new form.
Learn more about copying forms in our help guide.
