This module is perfect for many kinds of uses, for example table of contents, user guide or summary of joomla articles. I was searching a module like this for many hours without finding anything that could work like this. I also was ready to pay for an extension that allows me to place in a article the table of contents of my joomla articles. Finally I found this very good and useful module. So now I don't need to create menu items and sub menu items and sub sub... I create a complete table of content, with this module I only have to choose which categories article I want to show and a perfect ToC appears with links to every single articles. And it is free! I asked to the developer a little customization and immediatly I have it with a very good lesson about the correct use of the module. It was exactly what I was looking for. Thank you to the developer.
