If you need a section of your form to be duplicable (to allow users to add multiple duplicable sections when completing records), you can set this feature when creating your form template.
1. Go to "Edit Form Template" from the database that holds the form, or when in a database click on the "Edit Form Template" icon.
2. Once in the Form Builder, add a new section, check the box saying "Duplicable", then add the Section Singular and whether you want to enforce one section minimum. You can also prevent certain Groups from being able to edit that section (read more here).
You will need to enter in at least 1 field in order for the section to become visible. Note that this feature can only be added when you're creating a section, ie it's not available if you wish to update the Section.
Once you've completed adding your fields, save your form. Now when a user adds a record, they will be able to add duplicate sections to their record, as demonstrated below.
