The same java script is used through the site to: (1) slide the main menu,
(2) expand/collapse submenus, and (3) highlight the selected topic. That is
accomplished by a script tag with the src="Menu.js".
Any settings used
by the java script that are page specific must be set in a prefixing
script tag. In this case sSubMenu_Name is set to either null or the
submenu ID (remember null will do nothing and a submenu name will toggle the
status of the submenu).
This was a little tricky because any settings placed
in the script block with
the src set, are placed at the end of the script, hence can't be used correctly
in the src java script. Globals must be placed in a separate script block preceding
the src script block as demonstrated above.
