Notes

  • The current user must have permission to view the selected folder or knowledge center in the parameter.
  • Within a folder or knowledge center, the user can only see contents for which they have permission to view.
  • Each column displays items in alphabetical order, with folders always listed first.
  • Avoid using this component for offline mobile forms because tapping on a folder does not display its contents and tapping on a file does not download it when offline.
