Can't reorder items

[Cristian]

Hello, I am trying to reorder/sort items in my TreeList but it doesn't seem to work like this demo:

https://demos.telerik.com/aspnet-core/treelist/dragdrop

 

Every time I drag an items it looks like i can only add it to a parent but I can't drop it in a new position (see attached video).

So I have two questions:

1. How to enable the drop in between items?
2. How to disable to parent  functionality (I only need to allow the reordering on the same level)

Here's the code:

01.@(Html.Kendo().TreeList<SchoolInfoSectionViewModel>()
02.    .Name("treelistschool")
03.    .Columns(x =>
04.    {
05.        x.Add().Field(e => e.SectionId).Title(" ")
06.            .Template($"<div class=\"d-inline-flex\" role=\"group\">" +
07.                      $"<a href=\"../SchoolInfo/Edit/#= SectionId #\" class=\"btn btn-sm btn-secondary mr-1\">" +
08.                      $"<i class=\"fa fa-pencil\"></i></a>" +
09.                      $"<span class=\"text-muted mr-1\">|</span>" +
10.                      $"<a href=\"\\#\" data-val=\"#= SectionId #\" class=\"btn btn-sm btn-danger mr-1\" data-toggle=\"modal\" data-target=\"\\#deleteModal\">" +
11.                      $"<i class=\"fa fa-trash\"></i></a></div>")
12.            .Width(120)
13.            .Filterable(false);
14.
15.        x.Add().Field(e => e.SchoolInfoContent.ContentTitle).Title("Section Title")
16.            .Template($"<a href=\"../SchoolInfo/Detail/#= SectionId #\" >#= SchoolInfoContent.ContentTitle #</a>");
17.
18.    })
19.    .Editable(editable => editable.Move(true))
20.    .Reorderable(true)
21.    //.Filterable()
22.    //.Sortable(true)
23.    //.Toolbar(toolbar => toolbar.Search())
24.    //.Toolbar(t => t.Custom().Name("btncreateschool").Text("+ Create new section"))
25.    //.Search(x => x.Field(f => f.SchoolInfoContent.ContentTitle))
26.    .DataSource(x =>
27.            x.Read(read => read.Action("AllSchool", "SchoolInfo"))
28.            .Model(m =>
29.            {
30.                m.Id(f => f.SectionId);
31.                m.ParentId(f => f.ReportsTo).Nullable(true);
32.                m.Expanded(false);
33.                m.Field(f => f.UpdatedBy);
34.                m.Field(f => f.SchoolInfoContent.ContentTitle);
35.                m.Field(f => f.UpdatedOn);
36.                m.Field(f => f.IsPublished);
37.            })
38.    ))

For the record, I tried this like in the demo, but it throws a build error:
"error CS1660: Cannot convert lambda expression to type 'bool' because it is not a delegate type"

1..Editable(editable => editable.Move(move => move.Reorderable(true)))

Hi Cristian,

The reorderable option of the Kendo UI TreeList is relatively new. It should be available with the latest version that you have specified in the ticket. Is it possible for you to confirm that the utilized version of the project is 2020.3.1007 or at least 2020.3.915?
