How do I add Title to this SelectList? Or any other data-* HTML attribute?

SelectList.cs

public IEnumerable<SelectListItem> GetProducersSelectList()
{
    SelectList selectList = new SelectList(
        ProducersList
        .Select(
            producer =>
            new
            {
                Text = producer.ProducerNumber + " • " + producer.Surname + ", " + producer.Name,
                Value = producer.Id.ToString(),
                Title = producer.BusinessName
            }),
            "Value",
            "Text"
            );
    return selectList;
}
