Is there a way to expand or hide content?

In my organization's API guides, we sometimes need to list a lot (like, 30) API endpoints, which all are related to a specific functionality. Including such a list to a table or in the document body has a real negative impact on readability.

In our internal wiki (Confluence), I can create a table with an expand macro, so the user can toggle between viewing and hiding the list of endpoints.

Do you have any suggestions on how to work around this in ReadMe?
