Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Hi, I created something like this too some time ago. I used OPML to define the tree because OPML can be exported from a lot of "hierchical" savvy software (like mindmaps, ...).

However, I do eventually want to add support for pluggable input formats, and OPML would be a natural.
