[Solved] Treeview with multiple levels

[SoH]

Is there a way to get the treeview to work with multiple levels deep?

I've added an extra level here but it's not expanding:

Hello,

You can expand/collapse recursively  all nested nodes by using the `mapTree()` method available in the `@progress/kendo-react-treelist` package:

• https://www.telerik.com/kendo-react-ui/components/treelist/api/mapTree/

For convenience I have modified the provided example so you can test the suggested approach directly:
