Initially the dropdown values are loaded from the model, now it needs to be loaded static values. so I'm using the below type to load the dropdown, for this I can't able to add the CSS-class. Need advice

HTML

@Html.DropDownList("RoundOffInterval", new List<SelectListItem>
    {
    new SelectListItem{ Text="Select Roundoff Interval",Value=""},
    new SelectListItem{ Text="5",Value = "5" },
    new SelectListItem{ Text="10", Value = "10" },
    new SelectListItem{ Text="15", Value = "15" },
    new SelectListItem{ Text="20", Value = "20" },
    new SelectListItem{ Text="30", Value = "30" },})

Before i used the below type :

HTML

@Html.DropDownListFor(m => m.RoundoffInterval, new SelectList(Model.RoundoffIntervalList, "Id", "Name"), "Select Roundoff Interval ", new { id = "RoundoffInterval", name = "RoundoffInterval", @class = "select2_demo_4 form-control" })

Try with this format

C#

@Html.DropDownList("RoundOffInterval", new List<SelectListItem>
{
  new SelectListItem{ Text="Select Roundoff Interval",Value=""},
  new SelectListItem{ Text="5",Value = "5" },
  new SelectListItem{ Text="10", Value = "10" },
  new SelectListItem{ Text="15", Value = "15" },
  new SelectListItem{ Text="20", Value = "20" },
  new SelectListItem{ Text="30", Value = "30" }
}, htmlAttributes)

With htmlAttributes in your case is new {@class="select2_demo_4 form-control"}

Hope it help!
