Feature Request

Currently, KendoReact TreeList doesn't offer a built-in way to achieve selection behavior where selecting a parent node automatically selects all its children, and vice versa (deselecting all children deselects the parent). This feature would be highly beneficial for use cases involving hierarchical data structures where managing parent-child selection is crucial.

Proposal

Introduce a new option for the selectable prop, potentially named propagateSelection or recursiveSelection (similar to applyCheckIndeterminate provided in the TreeView component ). When set to true, it activates the desired behavior where selecting a parent selects all children, and deselecting all children deselects the parent.

It would be beneficial if the TreeList had the option to render a detail row out of the box via a prop as it is for the Grid.
