How can i print dynamic ListView Of List elements?

<ListView   ItemsSource= {Binding Source} >
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <ViewCell  >
                                <Grid>
                                    <Label Text={Binding SubList} ></Label>
                                </Grid>
                            </ViewCell>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>

obviously it doesn´t work, what another structure could i use?
