It looks like this fix only targets Windows. I'm seeing similar broken behavior on iOS + MacCatalyst with a CollectionView inside Expander.

Any chance you could take a look at the other platforms too?

[VladislavAntonyuk]

@brminnick as discussed at the meeting, I suggest merging it as it is (despite having some visual issues).

@brminnick @VladislavAntonyuk Do you guys have any predictions on when this will be completed? We can see several people having exactly this expansion problem within the CollectionView, I think this would be a good time for that

Thanks @VladislavAntonyuk for updating the expander under CollectionView and GridLayout.

I just tested it on Android and it works as expected, however it does not work on macOS and iOS (see screenshot below):

Android

macOS

iOS

On macOS/iOS, then you expand an item from the CollectionView all others disappear and it does not grow as expected. The same issue occurs on the horizontal items.

I will see if I can help with the macOS/iOS issue :)

@vhugogarcia has there been any progress made on this for iOS/macOS? I am currently stuck with it not working on iOS.
