I fixed it by using this method:

$form['field_provinces']['widget']['#ajax'] = [
      'callback' => [$this, 'retrieveContactLists'],
      'event' => 'change',
      'wrapper' => 'contact-lists-wrapper',
      'progress' => [
        'type' => 'throbber'
      ]
    ];

Breasy → created an issue. See original summary → .

Alright, thank you for your reply!

Hey larowlan

I have installed the core version of the forum module on my D9 website but as we are planning to move to D10, what would be your advise concerning the forum module?

Do we keep using the core module or should we use the contrib version?
