the text in the spinner wraps when scrolling the spinner. 

The issue happens in Time, TimeSpan, Date and DateTime pickers with day, month, hour spinners. 

The issue happens in maui 9.0.60 and 9.0.70 versions.

It works with maui 9.0.50 and lower versions

In MAUI CollectionView when scrolling an item into view, the exact position of the item after the scroll has completed can be specified with the position argument of the ScrollTo methods.

Please provide such option for Telerik MAUI CollectionView inside the ScrollItemIntoView method.

Provide a search option in the TreeView similar as in the DataGrid. 

When searching on loaded data it will highlight the items(folders, files) like in data grid.

I think filter is a separate feature that to implement together.

Take into account when filtering not to loose the selections that user done and can remove during the filter process from collection view.
