Access file drop area fields

Version: 10.4

You can use the Sitecore.Data.Fields.FileDropAreaField class to access the value in a field of type File Drop Area (FDA). The Sitecore.Data.Fields.FileDropAreaField.GetMediaItems method returns the media items associated with the FDA field.

You can implement a Web control based on the following example that generates an unordered list of links to the media items associated with an FDA field.
