In the Properties pane for a page or document, it is possible for there to be a list of collections under the Misc heading. These collections can include any number of items, but can be identified because their names are plural, indicating that there are more than one of them.

For example, collections can include Results, Textlines, Alternatives, Barcodes, and even Annotations.

Open the Collection properties window by clicking on the ellipses button in the Properties pane. This button appears only when you click on the entry.

The Collection window lists the following:

Members

This is a list of all members that are part of the collection. The Add and Remove buttons at the bottom can used to add new members or delete existing members from the collection.

Properties

This lists the properties for the selected member. You can organize the properties by category or alphabetically.
