"I then read that the Accordion Menu for Traction is configured specifically for the Traction menu, and can only be installed with the Site Shaper."
----No, we don't state that anywhere. You would just install the module in the backend of Joomla and then assign and configure it to the menu and module position that you would like. On the demo it's published to the "right" position. Please be sure you are installing the correct module and not another accordion module:https://www.shape5.com/component/option,com_docman/Itemid,96/task,cat_view/gid,91/
