Currently the control scrolls by group.

This would provide the option to stop the auto scrolling when the last item is hovered.

Enable the ComboBox to open its DropDown in up as well as down direction

The combobox lists in Windows 10 settings (see attached pictures) have an interesting behavior which could be integrated by Telerik combox controls. The behavior is as following: when the listbox is opened, it appears above the combobox control with the selected item highlighted. And the placement of the listbox can change if the first item is selected (displayed down direction) or the last item is selected (display up direction).

It's difficult to explain that with simple words, so I suggest to see attached pictures to understand my request.

The RadListBox has an attached property for mvvm binding of SelectedItems - https://docs.telerik.com/devtools/wpf/controls/radlistbox/features/selecteditemssource.

Please support SelectedItemsSource for RadComboxBox too.

When "TextSearchMode" is set to "Contains", IsEditable="True" and IsReadOnly="True": it should be possible to select all or some of the text and by pressing delete or backspace the selected text should be removed.
