Documentation about node settings values (for flow variables)

Where can I find documentation about node settings? Some nodes have for example a drop-down with a few options. Where do I find the available values so this options can be set through a flow variable.


How for example can I set Attribute Selection Type in Tree Ensemble Learner? Or the Attribute Sampling (columns?


this is not documented, you need to select the values in the dialog and than type them into your quickform or dialog for example.

Yeah but knowing the values in the drop down is requried to create a dropdown for the user.

OK, I could look at the source but also not very convinient.
