Drupal: Modal Node Edit Forms
Hier zeigt jemand wie man mit ctools modale Node Edit Formulare für Drupal 6 bauen kann:
Define the urls ajax/node/%node/edit and nojs/node/%node/edit. The idea is to use path similar to the normal drupal paths just prepended with what ctools modal needs. It needs are minor in that the url path must contain a string nojs and in this case a class attribute ctools-use-modal.
