You can do as follows:

@{
     List<SelectListItem> selectListItems = newSelectStaffList.ToList();
     selectListItems.Insert(0, (new SelectListItem { Text = "Select One", Value = "0", Selected = true }));
}
@Html.DropDownListFor(model => item.JobStaffId, selectListItems,new { @class = "form-control js-select js-noFilter hidden DDStaff DD2 ",multiple="multiple", size = "2", Id = "JobStaffId" + t })
