[for example:@Html.DropDownListFor(x => x.SelectedPlanCodeID, new SelectList(Model.PlanCodeList, "ID", "Plancode"), " Select ")]

DropDownListFor doesn't support it natively, you can either do a find/replace on the result of DropDownListFor or you can write your own HTML helper to do it. See this similar question:
