Simple question really - how do I use the select(ActionView::Helpers::FormOptionsHelper) with grouped options?

I have got it working with a select_tag (ActionView::Helpers::FormTagHelper) but I would really like to have it using a select tag to match the rest of the form. Is this possible?

My options look like this:

[
  ['Group 1', ["Item 1", "Item 2", "Item 3"]],
  ['Group 2',["Item 1", "Item 2", "Item 3", "Item 4"]]
]

whilst my view is currently:

%tr#expense
  %td
    = f.text_field :value
    = f.hidden_field :type, :value => mode
