PileFlowPanel contains PileFlowItem objects ("flow items"). A PileFlowItem is responsible for animating its element and can contain any FrameworkElement-derived class. The PileFlowCard class is used for displaying content with an optional mirror-like reflection in the PileFlowPanel beneath the content; this class is used in XAML to add elements to PileFlowPanel. The PileFlowPanel class also contains a label that can be configured to display the PileFlowItem data via the property ContentLabel. When the PileFlowPanel has focus, this sample lets the arrow buttons or the mouse wheel modify the selection. This feature is only available in the "Plus" version.
