I have a pretty complex custom tree in a custom section in umbraco, its got 3 or 4 levels at some points and many diffrent 'node types' -

I have sucessfully redered these - However I am finding creating the Angualr views and controllers to add/create and manage the data difficult.

After a bit more research I am startnig to think should I be using more than one tree?

At the moment I have got many many 'else if' statments like this:

     if (id == Constants.System.Root.ToInvariantString())
            {


                var myNodes = new TreeNodeCollection();

                foreach (var item in myService.GetAll(c => c.Brands))
                {

                    var node = CreateTreeNode("opco-" + item .Id.ToString(), "-1", queryStrings, opco.Name, "icon-globe-alt", opco.Brands.Any());

                    myNodes.Add(node);
                }
                return myNodes;

            }
            else if (id.StartsWith("opco-"))
            {.....}else if 
(id.StartsWith("nds-"))
{}

Is this incorrect, should I be using more than one tree............ one for each level?

Or is this ok... I'm gettin more confused by the day. lol
