Navigating through https://github.com/danchoi/kindlefodder I've found that some of the docs contain a neat section list. To view it, you have to click on the top of the page to reveal the options, and then a "Sections" block will apear, with a scrollable list of items. I was wondering how that is possible? How could I make an ePub/Mobi file with that?
The code for the doc generator is really old and unmaintained, and I couldn't find any information on how to generate that menu or even how to search for that.
