return options of options field

[froot]

how do I return all the options of an option field?

I have an option field on the children pages and need to list them.

The API-documentation says as follows…

$items = $fieldtypeOptions->getOptions($field);

but it doesn't work. 

Also unclear if $fieldtypeOptions is to be used as is or would that be replaced with my field? It's not apparent if you're not a pro, the API documentation lacks examples or explanations as usual.

Getting all possible options
This retrieves all possible options for the field, regardless of whether they are selected or not (there is no page involved here).

$field = $fields->get('countries');
$all_options = $field->type->getOptions($field);

thanks! I wonder though why the ->type-> part is not in the API doc

https://processwire.com/api/ref/fieldtype-options/get-options/

because without it, doesn't work
