Vertical stretching for ListViewItems

I have a List view with many ListViewItems, but each ListViewItem could have one or more lines of text.

All i need is force each ListViewItem to stretch vertically as its own content.

Is it posible with ListView ?

There is another control allow me to do that?

If you are using MVVM and DataTemplates to produce the ListViewItems dynamically they are doing this by default. This is an quick example of this.

MainWindow.xaml

<ListView ItemsSource="{Binding items}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <Label Content="{Binding text}" />
                <ListView ItemsSource="{Binding strings}">
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <Label Content="{Binding}" />
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

MainViewModel & ListItemViewModel

public class MainViewModel
{
    public List<ListItemViewModel> items { get; set; }
    public MainViewModel()
    {
        List<ListItemViewModel> things = new List<ListItemViewModel>();
        List<string> temp = new List<string>();
        for (int i = 0; i < 5; i++)
        {
            temp.Add(i + "");
            things.Add(new ListItemViewModel()
            {
                text = "item"+i,
                strings = temp.ToList<string>()
            });

        }
        items = things;
    }
}

public class ListItemViewModel
{
    public String text { get; set; }
    public List<string> strings { get; set; }

}

As stated below in the comments, this is a very quickly thrown together demo and the ViewModels do not contain any of the INotifyPropertyChanged events. The UI will not automatically reflect changes in the ViewModel because of this.
