### Current behavior

Hi
In the TreeList control when I Freeze first column and apply multi column header in some other column, then setting the filterable property for a column after multi column header is applied to some other column instead of the column on which it is set.
You can find a working sample here.
In this example note that I have set the filterable property false for field "Phone" but its effect is applied on "Position" field and its filters are hidden. Similarly if you apply filterable: false on "Extention" field then the filter on "Address" field will be gone.
Kindly provide a solution for this problem, also let me know if a work around exists for this issue.

Hi
Would like to request for Treelist with Server side paging and load childs on expand parent. Thank you.
The TreeList control doesn't allow for a fixed row of aggregates at the bottom of the control. I would like to have the option to enable a row of "Grand Total" aggregates that are aggregates of the whole data set. This row would be fixed at the bottom of the control and wouldn't be scrollable. This is functionality that the Kendo Grid has that isn't available in the Kendo TreeList.

Hi Team,
I'd like to request for the Kendo UI TreeList have the ability to export to Word.
Thanks!
if you look at this dojo (http://dojo.telerik.com/oSOloLuR) the attributes work for kendoGrid. If you change to a kendoTreeList, the conditional attributes do not work. Is there a different way to change the attribute? I tried in the template, but can't set the background-color style in the temple.
Code from dojo with kendoGrid changed to kendoTreeList:

Noticed an issue with Tree list pagination, after applying filter.Please find attached screen recorder for the same.
Same issue i had in my application, which was able to reproduce using the Telerik Demo's from https://demos.telerik.com/kendo-ui/treelist/index
--When it first load and minimize/collapse the parent it correctly shows page 1 as available pages.
-->Then Apply filter as shown in recorder, which then shows pages up to 5 where there were no records to display from page 2 to 5. Which is quite misleading.
Please find attached recorder.
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. http://demos.telerik.com/kendo-ui/grid/multicolumnheaders
Request to add Batch Editing feature for Kendo Tree List
