The ZT Accordion Menu is a simple module for Joomla 1.5 native. It allows you create an accordion menu for the sub level navigation using unordered lists and JQuery javascript library, and set "no conflict" mode to allow usage with mootools, and other libraries. No conflict mode removes the "$" operator from jQuery, allowing other libraries to use that operator.
