New feature request has start with the blog post : Form field help. It's a great post that explain how to extend a form to add a custom option help to show help message. I asked myself how to add this help message in an item choice of choiceType form. I wanted to make that like a choice_attr and callable function. But I cant. I fact ChoiceType create his children fields (Radio or Checkbox) with ChoiceView class and we can't add your custom options.

In resume we can't extend choice_options like this:

            ->add('dilem', ChoiceType::class, [
                'choices'     => [
                    'foo' => false,
                    'bar' => true,
                'choice_options' => function ($value, $key, $index) {
                    if ($value) {
                        return ['help' => 'My Help message'];
                'expanded'      => true,
                'multiple'      => false,
            ]) ;

I want to modify the code and create the pull request but can someone can accompany me to do it properly ?

I think this is the same feature request as #18318. So I am closing here as a duplicate.
