                  &lt;art:GridOptionsView ItemsSource="{Binding Items}" &gt;
                      &lt;art:GridOptionsView.ItemTemplate&gt;
                          &lt;DataTemplate&gt;

      &lt;ContentView.Content&gt;
          &lt;Grid Padding="0"&gt;
              &lt;StackLayout VerticalOptions="Center" HorizontalOptions="Center" Orientation="Vertical" Spacing="10"&gt;
                  &lt;Grid&gt;

                  &lt;/Label&gt;
              &lt;/StackLayout&gt;
          &lt;/Grid&gt;
      &lt;/ContentView.Content&gt;
      &lt;ContentView.GestureRecognizers&gt;
          &lt;TapGestureRecognizer Tapped="OnWidgetTapped" /&gt;
