Hello,

I noticed that all component of ComboBox (DropDownList, DropDownTree, MultiColumnComboBox) which have a GroupField doesn't provide a GroupTemplate

It would be very helpful to have one to further customize how we want the group to render

For example in my case, I want to customize items and groups to add checkbox on each level and parent checkbox will select/unselect children, but because I don't have access to group template I can't do it.

I think I can work something with the DropDownTree, but it will be kind of ugly as the component is not suited for multi selection and will not be related to the component selections

Thanks
Regards
Thomas
