At moment the Form Group does not support the HtmlAttributes() method. Is it possible to implement?

For example:

@(Html.Kendo().Form<Model>()
  .Name("exampleForm")
  ...
  .Items(items =>
  {
    items.AddGroup()
      .HtmlAttributes(...)
      .Items(i => {...});
  })
)

The Kendo Form should include native ListBox editor support including joining and swapping items between two ListBox's using ConnectWith.

To use a ListBox in the Kendo Form currently requires a custom editor which is overly complex.
