Interactive lesson

How can I show variations in an interactive lesson?
For example: There is a mate in 2 for white, but after White's first move Black has 2 options. I want to show both the options and their solutions.
Please advise.

You could make 2 chapters
One for each variation

I want to know if it's possible to do it in 1 chapter itself

I don't think you can do that with interactive lessons
