While using a Canvas App on Desktop, or when it’s embedded in Dynamics 365 CE, it’s a nice design decision to highlight the Gallery items on which your mouse is pointing on as you navigate/scroll.

Default Behavior

By Default, the Gallery Items remain visually static and don’t show any effect if you move your mouse over the items.


That’s because the Transition effect on the Gallery items is set to None by default.

Similarly, like Pop, Push will have the reverse effeect of pressing into the item hovered.

1. Again, when Gallery is selected, set the Transition to Push in the menu, save the changes and check again.
   
   
   The Push effect will be as follows –
