ASP.NET MVC DropDownListFor with Nested Properties in Model

I have two classes an Entry and Paradigm. The Entry class has a ParadigmId and a Paradigm property. So in my view I have @Model.Entry.Paradigm. How do I build a DropDownListFor using the newer syntax for the Paradigm model?

   // Entry Model
    [Bind(Exclude = "EntryId")]
    public class Entry
    {
        [ScaffoldColumn(false)] 
        public int EntryId { get; set; }
 .
        [Display(Name = "Type")]
        public int ParadigmId { get; set; }

        public virtual Paradigm Paradigm { get; set; }
    }

// Paradigm Model
public class Paradigm
{
    [ScaffoldColumn(false)]
    public int ParadigmId { get; set; }

    [Required]
    public string Name { get; set; }

    public List<Entry> Entries { get; set; } 
}

In my view I have @Html.DropDownListFor(model => model.Entry.ParadigmId, model.Entry.Paradigm). But the model is of type Paradigm not IEnumerable. Since Paradigm is part of my class (for Entity Framework Code First) I do not need to use a separate ViewData/ViewBag that is listed in most examples.

I Googled a bit and saw individuals using Helper/Extension methods to convert a model into a SelectList. What is the best way to use DropDownListFor in my model?

    @* Create View *@
    <div class="editor-label">
        @Html.LabelFor(model => model.Entry.ParadigmId)
    </div>
    <div class="editor-field">   
        @Html.DropDownListFor(model => model.Entry.ParadigmId, model.Entry.Paradigm)
        @Html.ValidationMessageFor(model => model.Entry.ParadigmId)
    </div>
