Forms that have collected responses can be archived, but not deleted.
You can archive a form by clicking on the icon on the far right of your dashboard, or by selecting the “archive” button on the form manage page.
Archived forms can be found by filtering your dashboard to “Archived”. You can search by form name, or drop sort by date, form name or form creator name.
An archived form can be re-opened by clicking “Un-archive” on the form manage page. This will bring the form back to the status it was in before it was archived.
