Hi,

I am looking for a tutorial that will show me how to add a new section and tree, I been working through the example in the docs:

https://docs.umbraco.com/umbraco-cms/v/13.latest-lts/extending/section-trees/sections

And

https://docs.umbraco.com/umbraco-cms/v/13.latest-lts/extending/section-trees/trees

But I hit a couple of issues:

Here is my Code:

using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; using Umbraco.Cms.Core; using Umbraco.Cms.Core.Actions; using Umbraco.Cms.Core.Events; using Umbraco.Cms.Core.Models.Trees; using Umbraco.Cms.Core.Services; using Umbraco.Cms.Core.Trees; using Umbraco.Cms.Web.BackOffice.Trees; using Umbraco.Cms.Web.Common.Attributes; using Umbraco.Cms.Web.Common.ModelBinders; using Umbraco.Extensions;

namespace UmbracoCMS.App_Code.HousingInformation { [Tree("housinginformation", "housinginformation", TreeTitle = "Blocks", TreeGroup = "housinginformationGroup", SortOrder = 5)] [PluginController("HousingInformation")] public class HousingInformationTreeController : TreeController { private readonly IMenuItemCollectionFactory _menuItemCollectionFactory;

    public HousingInformationTreeController(ILocalizedTextService localizedTextService,
    UmbracoApiControllerTypeCollection umbracoApiControllerTypeCollection,
    IMenuItemCollectionFactory menuItemCollectionFactory,
    IEventAggregator eventAggregator)
    : base(localizedTextService, umbracoApiControllerTypeCollection, eventAggregator)
    {
        _menuItemCollectionFactory = menuItemCollectionFactory ?? throw new ArgumentNullException(nameof(menuItemCollectionFactory));
    }
    protected override ActionResult<TreeNodeCollection> GetTreeNodes(string id, FormCollection queryStrings)
    {
        var nodes = new TreeNodeCollection();

        // check if we're rendering the root node's children
        if (id == Constants.System.Root.ToInvariantString())
        {
            // you can get your custom nodes from anywhere, and they can represent anything...
            Dictionary<int, string> blockMenuItems = new Dictionary<int, string>();
            blockMenuItems.Add(1, "Block Information");
            blockMenuItems.Add(2, "Block schedule");


            // loop through our favourite things and create a tree item for each one
            foreach (var mnuItem in blockMenuItems)
            {
                // add each node to the tree collection using the base CreateTreeNode method
                // it has several overloads, using here unique Id of tree item,
                // -1 is the Id of the parent node to create, eg the root of this tree is -1 by convention
                // - the querystring collection passed into this route
                // - the name of the tree node
                // - css class of icon to display for the node
                // - and whether the item has child nodes
                var node = CreateTreeNode(mnuItem.Key.ToString(), "-1", queryStrings, mnuItem.Value, "icon-presentation", false);

                nodes.Add(node);
            }
        }

        return nodes;
    }

    protected override ActionResult<MenuItemCollection> GetMenuForNode(string id, FormCollection queryStrings)
    {
        // create a Menu Item Collection to return so people can interact with the nodes in your tree
        //var menu = _menuItemCollectionFactory.Create();

        //if (id == Constants.System.Root.ToInvariantString())
        //{
        //    // root actions, perhaps users can create new items in this tree, or perhaps it's not a content tree, it might be a read only tree, or each node item might represent something entirely different...
        //    // add your menu item actions or custom ActionMenuItems
        //    menu.Items.Add(new CreateChildEntity(LocalizedTextService));
        //    // add refresh menu item (note no dialog)
        //    menu.Items.Add(new RefreshNode(LocalizedTextService, true));
        //}
        //else
        //{
        //    // add a delete action to each individual item
        //    menu.Items.Add<ActionDelete>(LocalizedTextService, true, opensDialog: true);
        //}


        return null;
    }

    protected override ActionResult<TreeNode?> CreateRootNode(FormCollection queryStrings)
    {
        var rootResult = base.CreateRootNode(queryStrings);
        if (!(rootResult.Result is null))
        {
            return rootResult;
        }

        var root = rootResult.Value;

        root.RoutePath = string.Format("{0}/{1}/{2}", Constants.Applications.Settings, "housinginformation", "overview");

        // set the icon
        root.Icon = "icon-hearts";
        // could be set to false for a custom tree with a single node.
        root.HasChildren = false;
        //url for menu
        root.MenuUrl = null;

        return root;
    }



}

}

I want to add custom menus for Block Information and Block schedule they both seems to want to call the edit.html in the back office section of the plugin.

I like it to do some thing like

/backoffice/Blocks

And

/backoffice/ BlockSchedual

Ect for other menu items I add.

Also I am finding when I click on "Block Information (Housing estate Information)" menu I am getting the settings menu and not the one I defined in code I have to click on it twice to get the correct menu.

If any one can point me in the direction of a tutorial that would be good. It need to be for version 13.

Thanks in Advance. Darren
