带有时间戳的自定义列表控件，如UI

我需要一个类似时间戳的列表控件，其中未选中的元素仅在用户单击时显示。但是，如下图所示，我只需要中央列表，而不是整个时间戳。

是否有任何具有类似功能的控件？或者如何建立一个？

编辑 - 使用Nasser AlNasser建议的ComboBox

所以我尝试编辑ComboBox的默认样式，几乎实现了我想要的外观。但是有一个小问题。

当我在本地计算机上运行应用程序时，下拉列表显示如下：

在模拟器上：

这是ComboBox样式：

ComboBox控件是您的最佳选择，它是UWP官方XAML控件的一部分： combobox-uwp 

<ComboBox x:Name="FontsCombo" Header="Fonts" Height="44" Width="296">
  //bind the ItemSource, or:
  <ComboBoxItem Content="Font A" />
  <ComboBoxItem Content="Font B" />
</ComboBox>

此外，您可以在此处找到默认样式：https://msdn.microsoft.com/en-us/library/windows/apps/mt299116.aspx

这使您能够根据自己的喜好重新设计样式：）。
