Type: Feature Request

This functionality is available in Kendo UI for Angular:


For example:

  • If you search "steven", the result should contain the parent item "Steven Buchanan" and all of its child items:

Bug report

DropDownTreeItemModel does not properly pass its HtmlAttributes members on populating DropDownTree with BindTo()

Reproduction of the problem

In .Net Core application, implement the following view:


and the following controller:

public IActionResult Index()
    ViewBag.Items = GetItems();
    return View();

public IEnumerable<DropDownTreeItemModel> GetItems()
    IDictionary<string, string> attributes = new Dictionary<string, string>
        { "style", "background: red" }

            List<DropDownTreeItemModel> items = new List<DropDownTreeItemModel>
        new DropDownTreeItemModel { Text = "Item 1", HtmlAttributes = attributes },
        new DropDownTreeItemModel { Text = "Item 2", HtmlAttributes = attributes },
        new DropDownTreeItemModel { Text = "Item 3", HtmlAttributes = attributes },
        new DropDownTreeItemModel { Text = "Item 4", HtmlAttributes = attributes },

    return items;

Current behavior

The HTML attributes will not be passed to the DropDownTree items.

Expected/desired behavior

The HTML attributes should be passed and present in the DropDownTree items.
