How to get the value of the linked element of the Bitrix infoblock?

Question

1C-Bitrix

There is an infoblock with the METHOD property, to which another infoblock is attached, containing several properties.
How to get the properties of 2 infoblocks and from 1 infoblock?
I use the following code to get properties:

<? $types = CIBlockElement::GetList(array(), Array('IBLOCK_ID' => ID,  'ACTIVE' => 'Y'), false, array('nTopCount' => 3),
            array('PROPERTY_BANNER', 'PROPERTY_TITLE', 'PROPERTY_SUBTITLE',
                'PROPERTY_METHOD'));
        while($type = $types->GetNext()):?>
        <?=$type['PROPERTY_METHOD_VALUE']?>
        <?php endwhile;?>
