When items are added to a collapsed group in the DataGrid, they are not marked as collapsed internally, which causes gaps to appear at the bottom of the control. These items are still considered during the measure phase, resulting in an inaccurate height calculation for the row content.

When hovering a shape with the mouse, it needs to change its visual state to the 'selected' state together with all the shapes on the left and all shapes on the right need to change their visual state to the 'not selected' state. When hovering away from the Rating control, all shapes need to display their current state - 'selected' or 'not selected' based on the Value property. This behavior can be useful to display the expected result if the hovered shape is clicked/tapped on.

Hello,

The CollectionView has a HeaderTemplate and a FooterTemplate. When using grouping, there is a GroupHeaderTemplate but no GroupFooterTemplate (like the default MAUI CollectionView has).

Can the GroupFooterTemplate be added to the CollectionView control?

Thanks!

There is a native toolbar on iPad, for example to apply bold, italic settings to the text, and this works on RichTextEditor only when the text is selected. Consider integrating this toolbar with the RichTextEditor operations.
