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?

@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.

Looking good. One issue I am looking at in windows is:

As you can see the items at bottom are being cut off with no image being displayed. It is not scrollable at all and items expand maybe one inch or so.

In android on bottom of page it expands as expected but fails to unexpand when clicked closed. It does remove image and text but the space is left open.

thank you @ne0rrmatrix, I will take a look at Windows, because it looks broken. Android at least renders correctly and I don't want to change the default cell size maui behavior.

@ne0rrmatrix , that is not an issue, just scroll. it is a part of listview

Yes I see that now. My bad. It looks good on my end and you have made all the requested changes.

thank you. I will update docs and merge PR in the morning
