// A cascading menu script by Fredrik Fridsten 2000 (c)
// Feel free to use this, but please mention in a comment in the code.

// Original Script can be found at: http://www.fridsten.se/
// Modified extensively by Heartland Business Systems http://www.hbs.net
// Portions of original code also found in nav.css

// Compatible with NN4+, IE5+, Opera, Omniweb, Safari, Mozilla and derivatives
// Thanks to Fredrick Fridstein for this easy to read, easy to use, wonderfully cross browser compatible script

// To configure the script:
// Change the nom value to the number of menus that you want to use
// Note: Always make sure that this is correct, otherwise you might get a javascript error.

// The phrases "images/opened.gif" and "images/closed.gif" should be referring to the
// pictures you might use.
// If you don't want to use images, just remove the mainIndOn and mainIndOff functions.
// Also remove the lines in the toggle function that refer to those.

// The input variables to the toggle function are the number of the submenu to open/close,
// starting with 1, and the number of pixels to move the objects below.
// For example toggle(2,60) opens/closes the second submenu and moves the objects below 60 pixels.
