I'm trying to only allow
certain file types (.xls, .doc, etc.) in an attachment field, and not seeing how
to do that. My attempts to use a Filter to do a wildcard search on the
various field types is not doing what I think it should. Has anyone
conquered this yet?
I think might have more
control over file types if I went to an attachment form, but then I'd lose
the drag and drop functionality that the users probably want more than they want
the file type limitations.
