In a similar vein to this: -

#81

I create a select:-

$field_settings = [

     'choices' => [
      'value' => 'label', 
    ],
    'return_format' => 'value',
];

->addSelect('select_field', $field_settings);

Apologies for sudo code but the result I expect to see is value but what's returned is label and even when set to both it still returns label.

I understand there is this option to add choices.

->addChoices(['red' => 'Red'],

Feel free to guide me in the proper way to do this cause I'm a bit lost.
