I discovered that you have to add a callback function in your functions.php file. See example below. Here is the link where I did find some info.

Sample Code

function getCities() {

$cities = [
“Paris” =>”Paris”,
“Marseille” => “Marseille”,
“Lyon” => “Lyon”
];

return $cities;

}

I can at least answer question 3. There is very little documentation on ‘choices callback’. I did discover that you have to add a callback function in your functions.php file. See example below. Here is the link where I did find some info.

}

Try using the indexing.

value1 = 0
value2 = 1
