Maybe this helps you a little bit ;)

The xaml:

The data:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        DataContext = new MyDataContext();
    }
}



    class MyDataContext
    {
        public ObservableCollection Outers { get; set; }


        public MyDataContext()
        {
            Outers = new ObservableCollection();
            Outers.Add(new Outer() { Name = "Herp" });
            Outers.Add(new Outer() { Name = "Derp" });
        }
    }

    class Outer
    {
        public string Name { get; set; }
        public ObservableCollection Actions { get; set; }

        public Outer()
        {
            Actions = new ObservableCollection();
            Actions.Add(new Inner { Name = "Test1" });
            Actions.Add(new Inner { Name = "Test2" });
            Actions.Add(new Inner { Name = "Test3" });
            Actions.Add(new Inner { Name = "Test4" });
            Actions.Add(new Inner { Name = "Test5" });
            Actions.Add(new Inner { Name = "Test6" });
            Actions.Add(new Inner { Name = "Test7" });
        }
    }


    class Inner
    {
        public string Name { get; set; }
        public ICommand OnClick { get; set; }
    }

And if you are using Commands... Try it with this example: ICommand
