Is there any way to disable few checkboxes in the Dropdown with multiple selection?

I am using RadzenDropDown with multiple selection. I want to disable few of the checkboxes of the items in the dropdown. Is there any way to do that?

No, this isn't possible at the moment. All items in a DropDown are enabled.

Isnt it possible with a Template for the item? Its very custom but it might work somehow. I´m gonna test this later today and see if I can come up with a solution.
