Nested Multiple Choice?

Anyone have a good example of a nested multiple choice activity?
Building a guided verifying trig functions activity and looking for students to choose a type of trig identity to apply, for example Pythagorean, Double Angle, Reciprocal, etc. After that choice is made another set of choices appear that are more specific sin2x=2cosxsinx or cos2x=cos^2x-sin^2x etc. Might try using a table instead. However if the wheel is already invented would make life easier.

This is a rough draft that I think may work.

Talking to myself but here is what I ended up with in the end.

Didn’t help, but still here for you, man.:clap:t2:

No problem. Just didn’t want to reinvent the wheel, but was a fun problem to try and code.
