Dear Telerik Support Team,

would it be possible to add Constrained Mode support for the TreeList, given that it already exists for the Grid?

The Grid's resizable input accepts "boolean | ResizeMode", so resizable="constrained" keeps the overall table width fixed while resizing. The TreeList's resizable input is boolean only, and we could not find an equivalent option.

In our application, Grid and TreeList are wrapped by two components that are supposed to look and behave identically. Without constrained mode, shrinking a TreeList column leaves empty space to the right of the table whenever no horizontal scroll bar is present; the table stops filling the available width, whereas a grid next to it still does.

We are currently working around this issue by adding an additional spacer column, but that relies on internal DOM details of the TreeList and is likely to break with future updates. Native support would allow us to remove the workaround.

Tested with version 23.4.0; the public API docs suggest this is still the case in the latest release.

Thanks a lot in advance!
