I'd use the JQuery UI calendar. It's so easy to add

>For the editor for your Dates, add a UIHint:
>

[UIHint("MyDateTimeTemplate")]

>
>Then create an editor template for it with the same name. For example:
>

@model DateTime?
>
>@Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty)) 
>< script type="text/javascript">
>	$("#@ViewData.ModelMetadata.PropertyName").datepicker({ dateFormat: 'mm/dd/yy' });
>< /script>

>As for defining a new class for the dropdown, I believe that is unnecessary. Providing the display field name and value field name should be enough to only include those in the resulting html.
