course index menu

Is there a way to show a tree-type navigation menu for a particular course or training where all the modules are listed (say on the left side) and when one module is clicked it expands to show a list of activities which can be selected to navigate to a specific activity so long as there are no prerequisites?

Am I just missing something

Am I just missing something basic? I'm asking about Opigno 2. The LP Steps blocks provides close functionality to what I need, but is it possible to drill down to activities or some other sub-module structures?
