在列表视图中使元素可水平滚动

Question

如何使listview在另一个listview中水平滚动？父列表视图是可垂直滚动的。

这是xaml部分

<ListView Visibility="Visible" Loaded="feedList_Loaded"  ShowsScrollingPlaceholders="True" ItemContainerStyle="{StaticResource ModifiedListViewItemContainerStyle}" IsItemClickEnabled="True" x:Name="feedList" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0,10,0,0">
                        <ListView.ItemContainerTransitions>
                            <TransitionCollection>
                                <EntranceThemeTransition/>
                                <ReorderThemeTransition/>
                                <RepositionThemeTransition/>
                            </TransitionCollection>
                        </ListView.ItemContainerTransitions>
                        <ListView.ItemsPanel>

                                ............

我已尝试将stackpanel，pivot，hub放在子列表视图中，但没有任何效果。
