Enhancement: optgroup tag support to ListBoxFor

[mmunnis]

Very handy for grouping items in a list box.

Well, regular Html.ListBoxFor does not have support for this tag. I'm fine with extending this functionality, but what do you think syntax should be for this?

[mmunnis]

Maybe something like a Group class.

public class Group<K, T>
{
    public K Key;
    public IEnumerable<T> Values;
}

Then allow the user to pass an IList<Group<K, T>>

Have the helper accept something like this:

@f.FormGroup().ListBoxFor(m => m.MyModelField, Model.MyPassedGroup, mpg => mpg.Values.Id, mpg => mpg.Values.Name).OptLabel(true).LabelValue(mpg => mpg.Key)

That's pretty loose, just thinking out loud.
