Answer 1

I use this extension:

public static MvcHtmlString CheckBoxListFor(
    this HtmlHelper htmlHelper,
    Expression>> expression,
    IEnumerable multiSelectList,
    Object htmlAttributes = null)
{
    // Derive property name for checkbox name
    var body = expression.Body as MemberExpression;
    if (body == null)
        return null;

    String propertyName = body.Member.Name;

    // Get currently select values from the ViewData model
    IEnumerable list = expression.Compile().Invoke(htmlHelper.ViewData.Model);

    // Convert selected value list to a List for easy manipulation
    var selectedValues = new List();

    if (list != null)
        selectedValues = new List(list).ConvertAll(i => i.ToString());

    // Create div
    var ulTag = new TagBuilder("ul");
    ulTag.AddCssClass("checkBoxList");
    ulTag.MergeAttributes(new RouteValueDictionary(htmlAttributes), true);

    // Add checkboxes
    foreach (var item in multiSelectList)
    {
        ulTag.InnerHtml += String.Format(
            "
{3}
",
            propertyName,
            item.Value,
            selectedValues.Contains(item.Value) ? "checked=\"checked\"" : "",
            item.Text);
    }

    return MvcHtmlString.Create(ulTag.ToString());
}
