As discussed on the forum (http://www.telerik.com/forums/virtualization-for-treelist) please improve the rendering/scrolling/expanding/collapsing performance of TreeLists with many expanded rows.

Grids support virtualization and work well with hundreds of thousands of rows (http://demos.telerik.com/kendo-ui/grid/virtualization-local-data). Perhaps virtualization can be added to TreeLists to achieve similar results?

Much like how the Grid has column grouping, it would be nice if the TreeList had this as well.

I would like to use drag and drop on treeList to reorder rows (with same parent) like on treeView or at least to have same events (drag, dragstart, dragend, drop), where I'll be able to change behaviour.

Great work on this control boys.... I reckon it needs Filter Row, Multiple Column Sort, Paging to make it consistent with the grid.

Request to add Batch Editing feature for Kendo Tree List

Please, add for TreeList support of setOptions and getOptions methods.

Hi.

I would like the ability to specify a template for the toolbar in a TreeList, much like the ability in the Grid.

Thank you.

Support inline editing in Treelist

Hi

Would like to request for Treelist with Server side paging and load childs on expand parent. Thank you.

apply a row template to the TreeList !

Would like this option just like the regular grid has:
http://demos.telerik.com/kendo-ui/grid/filter-multi-checkboxes

The TreeList needs a DetailRow with DetailTemplate just like the Grid has.  The Grid does not support Hierarchial data that has more than one level of depth but the TreeList does and yet has no Detail Row.  Please add a Detail Row.

Is there any support for checkbox columns in the treelist to behave the same way as the kendoTreeView checkboxes? 

(ie, checking or unchecking parent should check/uncheck all children? and checking or unchecking children should update parent check state (possible indeterminate states))

Please add keyboard navigation to the TreeList, just like the same feature in the Grid

Steps to reproduce bug:

• Navigate to demo with Multi-columns header https://demos.telerik.com/kendo-ui/treelist/multicolumnheaders
• Click on "Edit this example" button
• On dojo edit code to add needed lib:
• <script src="https://kendo.cdn.telerik.com/2019.1.220/js/jszip.min.js"></script>

• add also toolbar: ["excel"] on config options
• Run dojo and hit export

The result has broken Headers

It would be nice if there was an option to not retotal the entire table if you expand a level in the treelist.  We use the table for lazy loads, so each level already has the total, we're just getting the details.

Please consider adding persis selection functionality to the TreeList. Such is available in the Grid:

Kendo tree list does not support column resize for touch devices. It would be very helpful if this can be considered since our application supports touch devices and without column resizing feature in kendo tree list columns it is very difficult to read the text in tablets, etc
