/*
 * menuDropdown.js - implements an dropdown menu based on a HTML list
 * Author: Dave Lindquist (dave@gazingus.org)
 *
 * Originally from http://gazingus.org/dhtml/?id=109
 *
 * mfischer, 2003.05.07: reworked for own purposes
 * - Open menus with onmouseover event
 * - use timeout to closemenu when mouse not over
 * - renamed all identifier names so we've no namespace clashes
 *   (lwm - light weight menu)
 *
 * mfischer, 2003.05.08:
 * - use getPosition function to get left/top offset if menu is contained in other elements
 *
 * Last time tested: 2003.05.08:
 * Works in: MSIE55+, MacMSIE51, Win/Gecko, Win/Opera 7.1
 *
