Please see:

This is one of your demo's with simply adding scrollable: false.

Uncaught TypeError: Cannot read property 'appendChild' of undefined

We need the tree list without a scroll bar as it is causing alignment problems. The alignment is fine until scrolling right to the bottom.

Is there a workaround if this is not immediately fixable?

Please help.

Hello, Clinton,

It is a requirement for the The Kendo UI TreeList with locked columns to be scrollable. The treelist has the same requirements as the grid and this is the first one - to enable scrolling:

I am not able to reproduce the misalignment in the provided Dojo and did not find any known issues logged  in our repository. Could you let me know the steps to take so I can reproduce it? and look for a workaround and log a bug so we can fix is in a future release?

Kind Regards,
