TreeList with groupable header columns

[Dennis]

Hey Folks,

is it possible to achieve the same functionality that the grid component offers ( groupable header columns ) in the TreeList? The documentation does not mention something like that and i did not get it to work.

Is my only option to use the grid component with dynamic subgrids?

Hi Dennis,

Currently, the Kendo TreeView does not support Groupable Header Columns like the Kendo Grid.  There is a feature request in our Kendo UI Feedback Portal which you can add feedback and upvote the idea.  

For more information about the Kendo Grid grouping, here is our documentation and a live demo.

Hi,

I have the same question to the TreeList. This functionality is very important for us.

Will it be possible in the future, as soon as possible?

I was looking for information about this, but i can't find anything.

Hello Lukasz,

As of R3 2018, this functionality has been added to the Kendo UI TreeList.  As for resources, please take a look at the following live demo of the Kendo UI TreeList with MultiColumn Headers and our documentation.

Hello Patrick,

My mistake. This is not exactly that what we need. We need functionality where user can grouping by drag and drop column header like in the grid.

On this page with the grid demo https://demos.telerik.com/kendo-ui/grid/index is example where the user can drag header colum and drop on "grouping section". This same functionality we need use in the TreeList. We want grouping (by drag and drop) only main rows (rows without parents), if it is possible.

Hello Łukasz,

Thank you for the clarification pertaining to dragging the header column and dropping it in the grouping section.  This functionality is not included with the Kendo UI TreeList.  That being said, I have created a new feature request with a vote on your behalf asking for this to be added in future releases.  

Please feel free to reply back within the request to share any additional details with our developers to consider pertaining to the matter and follow the request for updates.

Column menu doeesn't work for columns which are grouped together under a single column for kendo treelist. I am using kendo jquery. Please advise on the fix.

If you are referring to the Kendo UI TreeList with MultiColumn Headers, our live demo appears to be working as expected with the Columns menu functionality.  I hope this resource helps!

column menu is not appearing for computed columns..

[Patrick | Technical Support Engineer, Senior]

To get a better understanding of the mentioned behavior, please feel free to share an example.  To potentially help you get started, here is a Progress Kendo UI Dojo with aggregation, multi-column headers, and a column menu functionality working as expected.

please add column menu to this example. it will be helpful.

Here's how you can add the columnMenu functionality to the Kendo UI Grid including in the referenced KB.

        //Grid definition
        var grid = $("#grid").kendoGrid({
            columnMenu: true,
            //.....
        }).data("kendoGrid");

Hope that helps!
