AJAX parent selection on forms (completed)

The current parenti selection box on categoryi and containeri forms does not update when a new container is selected. See http://drupal.org/node/41279 for the bug report of this.

It would be really cool if, when a new container was selected on a form, some AJAX magic kicked in, and automatically re-populated the parent selection box to match the new container (without having to reload the page). The magic would degrade reasonably gracefully without JavaScript, to the way it is now: that is, right now you have to change the container, then save the node, then go back and edit it to select a new parent.

Assigned to: nobody.

Status: completed.
