| Nov 27, 2017 at 11:53 | comment | added | Joum | I'm struggling a bit with your remarks. Can you point me to some documentation regarding this? | |
| Nov 27, 2017 at 10:28 | comment | added | 4uk4 | You populate the options in the form rebuild. The form build function knows that it is rebuilding when $form_state is filled with user input, which it is not on the first build. | |

@4k4 thanks for your feedback, but I'm not sure what you mean. My dependent select element already exists in the form when it is first built, it just doesn't have the #options populated. After I populate them in the AJAX callback, they show up in the markup, but aren't available in the submit hook to be processed. Can you suggest how to handle this?
