Hello, @bluesboy!
You can use our Accordion app in the app center for this purpose. Take a look at it here: https://www.weebly.com/app-center/faq-accordion
If you'd like something different and are familiar with HTML, Javascript or jQuery. Try searching Google for collapsable text panel and your preferred coding method html or javascript or jQuery depending on what you are comfortable with.
other search terms could be collapsable text link and show/hide text +coding method.
The following third party site provides an example of how to create this using Javascript

Note that we do not support custom code and cannot guarantee the code you decide to use will work on Weebly. I only personally recommend that you stay away from W3schools for code.
I hope this helps. Good luck!
