Here is a sample... use this...hope it helps...

HTML

<listbox x:name="TeamListbox" horizontalalignment="Left" height="Auto" verticalalignment="Top" width="Auto" style="{StaticResource ListBoxStyle1}" itemtemplate="{StaticResource DataTemplate1}" xmlns:x="#unknown">               
</listbox>

The definitions for datatemplate is

HTML

<phone:phoneapplicationpage.resources xmlns:phone="#unknown">
               <datatemplate x:key="DataTemplate2" xmlns:x="#unknown">
		<grid>
                  <textblock margin="0,0,1,0" fontsize="25" foreground="Green" fontweight="SemiBold" textwrapping="Wrap" text="{Binding }" d:layoutoverrides="Width, Height" xmlns:d="#unknown" />
		</grid>
	      </datatemplate>
	      <datatemplate x:key="DataTemplate1" xmlns:x="#unknown">
                 <stackpanel>
                   <textblock margin="0,0,1,0" fontsize="32" foreground="White" fontweight="Bold" textwrapping="Wrap" text="{Binding TeamName}" d:layoutoverrides="Width, Height" tap="TextBlock_Tap" xmlns:d="#unknown" />
                  <listbox x:name="InnerLsitbox" tag="{Binding TeamName}" itemtemplate="{StaticResource DataTemplate2}" itemssource="{Binding TeamMembers}" visibility="Collapsed" />
                </stackpanel>
              </datatemplate>
</phone:phoneapplicationpage.resources>

In code-behind,
define your own class

C#

 public class Teams
    {
        public string TeamName { get; set; }
        public List<string> TeamMembers { get; set; }
    }
</string>

Initilalise the collection and fill with some dummy data

C#

ObservableCollection<teams> teams ;
        private FrameworkElement expandedElement;
        public MainPage()
        {
            InitializeComponent();
            teams = new ObservableCollection<teams>();
            InitializeTeams();
            TeamListbox.ItemsSource = teams;
        }

        public void InitializeTeams()
        {
            teams.Add(new Teams() { TeamName = "India", TeamMembers= new List<string>  () { "aaaaa1", "sssssssss1", "ddddd1", "fffffffffff1", "zzzzzzz1", "ccccc1" } });
            teams.Add(new Teams() { TeamName = "Australia", TeamMembers = new List<string>() { "aaaaa2", "sssssssss2", "ddddd2", "fffffffffff2", "zzzzzzz2", "ccccc2" } });
            teams.Add(new Teams() { TeamName = "Srilanka", TeamMembers = new List<string>() { "aaaaa3", "sssssssss3", "ddddd3", "fffffffffff3", "zzzzzzz3", "ccccc3" } });
            teams.Add(new Teams() { TeamName = "South Africa", TeamMembers = new List<string>() { "aaaaa4", "sssssssss4", "ddddd4", "fffffffffff4", "zzzzzzz4", "ccccc4" } });
            teams.Add(new Teams() { TeamName = "England", TeamMembers = new List<string>() { "aaaaa5", "sssssssss5", "ddddd5", "fffffffffff5", "zzzzzzz5", "ccccc5" } });
            teams.Add(new Teams() { TeamName = "West Indies", TeamMembers = new List<string>() { "aaaaa6", "sssssssss6", "ddddd6", "fffffffffff6", "zzzzzzz6", "ccccc6" } });
        }
</string></string></string></string></string></string></teams></teams>

In the tap event, handle the visibility of innerListbox like this

C#

private void TextBlock_Tap(object sender, GestureEventArgs e)
        {
            if (expandedElement != null)
                (expandedElement as ListBox).Visibility = System.Windows.Visibility.Collapsed;
            ListBox ll = (((sender as TextBlock).Parent as StackPanel).Children[1] as ListBox);
            expandedElement = ll;
            ll.Visibility = System.Windows.Visibility.Visible;
}
