Hi! I don't know if this is of any help, but I created a simple example of how a block of text could appear based on a dropdown menu choice https://observablehq.com/@triptych/text-and-choices

Well, I got ambitious and created this interactive story "engine" that show images/text based on a dropdown choice. I hope it's useful! https://observablehq.com/@triptych/interactive-story

Wow!!! This is so much work and I really appreciate it, thank you! This is a massive help and I'm SO excited and grateful.
