NavigationView animation bug

[Tentex1]

Describe the bug

When the NavigationViewItem under NavigationViewItem 2 (i.e., moving from index 0 to index 2) is selected, the blue pointer at the beginning of the NavigationViewItem teleports to the other selected NavigationViewItem.

Why is this important?

It's a visually very absurd distortion.

Steps to reproduce the bug

I will use the "MVVM Toolkit Sample App" as an example.

1. Open NavigationView

2. Building Blocks > Source Generators > ObservableProperty

3. Building Blocks > Source Generators > INotifyPropertyChanged

And yes, you saw the blue indicator teleport.

isnt this like an intented behavior?

I believe as long as the items are at the same nested level, the intended behaviour is for the selection indicator to "zip" between the positions with a bit of a stretch in height.

Obviously this is "by-design". The older NavigationView in UWP (prior to winui2) does have the indicator flying over all NavigationViewItems.

Don’t you think this is really ridiculous? Even if it was left that way on purpose, it’s still sooo ridiculous

No, it is in keeping with the motion and animations that are present in WinUI controls like the Progress Bar and Ring

Hi @Tentex1, this behavior is intended and by design. So, closing this bug.
