What are Admin Items?
Admin Items are items that appear only when viewing and editing results. They're completely hidden from form users. This provides a way to make "for office use only" sections on your form, or to add additional metadata to a result.
Creating Admin Items
Create Admin Items by adding or editing form items and enabling their "Admin Item" setting. Almost every item has an "Admin Item" setting, including Formatting Items.
You can also multi-select a group of items and edit "Admin Item" for the group all at once.
Viewing Admin Items
Admin Items appear in all results formats, including: when you edit results, Notification emails, Exports, Reports, etc. As with all items, you can hide them in results using Results Views.
Because Admin Items aren't part of your form when form users are completing it, Rules using Admin Items as criteria may not work as expected. It's best to avoid mixing Admin Items with Rules.
Remember which items you've made Admin Items. If there's an item that doesn't seem to show up when viewing your form, check to see if its "Admin Item" setting has been enabled.
