An illegal choice has been detected. Please contact the site administrator.


The form system automatically validates the selected value of a select and only allows those which are defined in '#options'. There is no way around that in D6, in D7, there is a flag to disable that.

You need to use #ahah and rebuild the form on the serverside. The following modules might be useful to you:

  • http://drupal.org/project/ahah_helper (for building it yourself)
  • http://drupal.org/project/hierarchical_select (Maybe you can extend that...?)
