Looking for an expand-on-click functionality plugin

Hey guys

I’m looking for a plugin/theme/something that lets me do the following:

1. Imagine we have a blog-post or a one-page theme with different sections or chapters (eg. headline, excerpt, chapter 1, chapter 2 etc.)

2. Somewhere in each chapter/section, there would be a button or an area that when hovered or clicked would expand.

3. When the button or area is activate by click or hover, a section with a description would appear somewhere on the screen until clicked again, or the hover is removed.

This is supposed to be used for a presentation of a strategy that is currently in printed-folder-format. The folder consists of several chapters, and each chapter describes a situation, and three relevant considerations to make in regards to solving a problem in the situation. So when I hover/click an area in the text or on the page, one or all three considerations should become available for me to read on the screen.

Hope someone can help inspire me. I’ve found some image-hover-techniques that might be tweaked into working, but they seem like workarounds with potential risks.
