Hey guys, could any one point out any advice or any help with my code to convert the first level of my site in groups of 3? 

@inherits umbraco.MacroEngines.DynamicNodeContext
@helper traverse(dynamic node)
    {
    var maxLevelForSitemap = String.IsNullOrEmpty(Parameter.MaxLevelForSitemap) ? 4 : int.Parse(Parameter.MaxLevelForSitemap);
    var values = new Dictionary<string, object>();
    values.Add("maxLevelForSitemap", maxLevelForSitemap);
    var items = node.Children.Where("Visible").Where("Level <= maxLevelForSitemap", values);
    if (items.Count() > 0)
    {
        var root = Model.AncestorOrSelf(1);
        var className = "level" + @node.Level;
        
        
        
          <ul class="@className">
            @foreach (var item in items)
            {
                <li>
                    <a href="@item.Url">@item.Name</a>
                   @traverse(item)
                </li>
            } 
           </ul> 
        
    }
}
<div class="sitemap"> 
    @traverse(@Model.AncestorOrSelf())
</div>

Any ideas? 

I have tried making if statements if node.level == 1 then make it into groups, but didnt work at all.
