I need one option to update the other in angular

I have a plunker set up http://plnkr.co/edit/fZ6akOYipzZ7ym8dliCV?p=preview

I want the first list to filter the group in the next list. It seems like it should be simple but i cannot seem to get it to function as desired. Any help will be appreciated.

You need to use just filter the first array with .filter method on the array, and check to see if the type is equal to the other type in a function (like get(option2))

<select id="unitTypes_speciality" name="speciality" data-role="none" data-ng-model="speciality" 
ng-options="p as p.label group by p.type for p in get(options2, type)"><option>None</option></select>

$scope.get = function(myarray, type) {
  return myarray.filter(function(value) { return value.type == $scope.type.label })
}
