I've got a form that needs to have either a 'file' or 'managed_file' type field in it for uploading files via the form. Is there an attribute that can be set on the form item render array that will allow multiple/unlimited files to be uploaded via the one form item?
For example, when you add a new field via the admin UI to a content type, select the 'file' type widget and then in the field settings set the number of values to 'unlimited' - that's the sort of behavior I'm looking for in this file field via the forms API. Thanks in advance for any pointers!
