Are there any example on how to use this package for tree data?

Hi, Spatie team. This is not an issue, but more about practical example on how to use this package for building tree menu. I think there are someone who need this package to build complex tree menu, with nested depth. And probably the data is in a multi-dimensional array. I think it would be nice if the docs can tell more about how to build this programmatically.

Thank you.
