DropDown with section lines

Hi,

How can i create an Dropdown with section lines that are grayded out and not selectable. And then as an override of the RadzeDropDown and adding the localisation. The temple can have disabled RadzenText, but these are still selectable in the DropDown, the source i use is a List,

public class EnumValue
{
    public int ValueInt { get; set; }
    public string Text { get; set; }
    public bool Disabled { get; set; } = false;
}

Heavily customized DropDowns with custom selection can be found here:
