Hi,

I am following this article to create a custom section in Umbraco: http://www.enkelmedia.se/blogg/2013/11/22/creating-custom-sections-in-umbraco-7-part-1.aspx.

This is the source code:

 [PluginController("CustomSection")]
    [Umbraco.Web.Trees.Tree("CustomSection", "CustomSectionTree", "My custom section", iconClosed: "icon-doc")]
    public class CustomSectionTreeController : TreeController
    {
        protected override TreeNodeCollection GetTreeNodes(string id, FormDataCollection queryStrings)
        {
            var nodes = new TreeNodeCollection();
            var item = this.CreateTreeNode(id, "-1", queryStrings, "My item", "icon-truck", true);
            nodes.Add(item);
            return nodes;

        }

        protected override MenuItemCollection GetMenuForNode(string id, FormDataCollection queryStrings)
        {
            var menu = new MenuItemCollection();
            menu.DefaultMenuAlias = ActionNew.Instance.Alias;
            menu.Items.Add("Create");
            return menu;
        }
    }

When rendered inside Umbraco back office, I am getting this:

It keeps on adding sub items the more I expand. Any idea what might be going wrong?

Thanks
