AngularJS, Populating dependent Combobox

Question

What I am trying to achieve is to populate a child combobox with items which depend on a \'parent\' combobox.

To clarify the - or better my - problem, I have created

Answer 1

You should refer currentGroup to populate the options inside items combobox:

You dont need $scope.currentItems at all. So just update the last 2 lines inside the controller to:

$scope.currentItem = $scope.currentGroup.Items[0];  

Now to remove the empty option, use super easy and light-weight ng-change:

Define the corresponding change handler in the controller:

$scope.groupChanged = function(){
    $scope.currentItem = $scope.currentGroup.Items[0];
}
