Answered Trying to include child resources in Wayfinder submenu for different parent

offsetChildren=`parent_id|resource_id_of_child:desired_menuindex,resource_id_of_2nd_child:desired_menuindex||repeat pattern for each parent as needed

offsetChildren=`4|95:998,23:999`

$this->offsetParents //contains the ids of the parents set in the param
/*Array
(
    [0] => 4

*/
$this->offsetChildren //contains the adoptive children [key] with parent and menuindex
/*
Array
