I don´t know if i understand well your problem.
If so, my suggestion is:
-> Do a projection of your model, converting it to SelectListItem List, and
pass into DropDownList Html Helper:
Example 1 - random data:
@Html.DropDownList("SelectedSiteId", new List<SelectListItem>() { new
SelectListItem() {Value = "1", Text = "Site 1"} })
Example 2:
Step 1: Pass data from controller to view:
-> Way 1: ViewBag.DropDownData = new List<Site>(); // fill data
-> Way 2: Strongly typed view.
Step 2: Doing the projection:
@Html.DropDownList("SelectedSiteId", (ViewBag.DropDownData as
List<Site>).Select(sel => new SelectListItem() { Value = sel.ID, Text =
sel.Title }).ToList())
