question

answer_box works great for markdown.

Would it be possible to also use it to fold away running code? My intention here is just to hide from view, not remove from the notebook.

I don't know how to do that. But someone else might. Personally, I'd just use Pluto's standard hide cell feature for code cells I don't want to distract students. If I want them to go back and inspect it later, then I just write that in the instructions.
