Solution 1
By using the proper DropDownListFor overload:
@Html.DropDownListFor(
model => model.ZipFile,
new SelectList(ViewBag.ZipFiles),
"-- please select a zip file --"
)
Solution 2
@Html.DropDownListFor(model => model.Country, new List<SelectListItem>
{
new SelectListItem { Text = "India", Value = "1"},
new SelectListItem { Text = "USA", Value = "2"},
new SelectListItem { Text = "Sreelanka", Value = "3"},
new SelectListItem {Text = "Africa",Value="4"},
new SelectListItem { Text = "China", Value = "5" },
new SelectListItem { Text = "Austraila", Value = "6" },
new SelectListItem { Text = "UK", Value = "7" }
}, "Select Country",
new {@Style = "Width:500px;height:40px;",
@class = "form-control input-lg"})
Solution 3
In the controller, when you set ViewBag.ZipFiles, add a SelectListItem to that collection.

@Html.DropDownListFor(model => model.ZipFile, new SelectList(ViewBag.ZipFiles))
The above code creates me a select list just fine. But I want to make the selection optional. Unfortunately there is no empty option and I'd like to add one in. How would I do this?
