If you check the menu on the website I am currently working on:
www.appa.qc.ca/joomla you will see that the Accordion menu I have setup on the left side shows the 3rd level menus aligned with the 2nd level menus.
The 4th and 5th elements in the menu are supposed to be 3rd level options but are aligned like 2nd level options. Could it be because the name of the links are too long?
