Explanation of exmplmenu_var.js file.

At first we will discuss the general layout of the file and later we go into more detail for every variable and the array structure.

The red colored items belong the the Javascript syntax and are case sensitive and critical. Var will generate an error, so will VAR.
The quotation marks are also needed, even when a text variable is left blank the quotation marks are needed. (An empty text string is not the same as no string)
The black colored items belong to the menu script and must not be changed or deleted.
The blue items can be changed and control the behavior and appearance of the menus.

SecLineFrame 
Text string- When the menus are used in a frameset this is the name of the frame where the sub levels of your menu are located. (see creating the frameset).

The menu tree

All element names start with Menu

The first element on the first level is called Menu1.
The second element on the first level is called Menu2.
The third element on the first level is called Menu3 ,etc.
If Menu1 has sub elements, the first of those is called Menu1_1, the second Menu1_2, etc.
If Menu1_2has sub elements, the first of those is called Menu1_2_1, the second Menu1_2_2, etc. 
The menu tree will look something like:

Menu1 					the first element of the first level
	Menu1_1				the first sub element of Menu1
	Menu1_2				the second sub element of Menu1
		Menu1_2_1			the first sub element of Menu1_2
		Menu1_2_2			the second sub element of Menu1_2
	Menu1_3				the third sub element of Menu1
		Menu1_3_1			the first sub element of Menu1_3
			Menu1_3_1_1	the first sub element of Menu1_3_1
			Menu1_3_1_2	the second sub element of Menu1_3_1
Menu2					the second element of the first level
Menu3					the third element of the first level
	Menu3_1				the first sub element of Menu3
		Menu3_1_1			the first sub element of Menu3_1
	Menu3_2				the third sub element of Menu3

There can be as much elements and sublevels as you need.
The order nor the layout of the menu tree is important. You could also build a tree like this: 
Menu1_3_1_2
Menu3
Menu1
Menu2
Menu1_3_1_1
Menu1_1
Menu3_1_1
Menu1_2
Menu1_2_1
Menu1_2_2
Menu1_3
Menu1_3_1
Menu3_1
Menu3_2 

The variables of the menu tree

Each element must have a text to show, a link to link to and the number of sub elements in the next level.
On top of that each element starting a new level (that is each element with it's name ending on 1) must also have the element width and element height in it's array.
 
For the above menu that would mean:

Menu1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
    Menu1_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
    Menu1_2=new Array("text to show","Link to link to",No of sub elements);
        Menu1_2_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
        Menu1_2_2=new Array("text to show","Link to link to",No of sub elements);
    Menu1_3=new Array("text to show","Link to link to",No of sub elements);
        Menu1_3_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
            Menu1_3_1_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
            Menu1_3_1_2=new Array("text to show","Link to link to",No of sub elements);
Menu2=new Array("text to show","Link to link to",No of sub elements);
Menu3=new Array("text to show","Link to link to",No of sub elements);
    Menu3_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
        Menu3_1_1=new Array("text to show","Link to link to",No of sub elements,element height,element width);
    Menu3_2=new Array("text to show","Link to link to",No of sub elements);

Elements that doesn't need element height and element width, may have them, but they won't be used.
 

Text to show 
Text string- What you want to show in the element. It can be text, an image or infact any part of a html document including tags
To show an image it must look like "<img src='MyImage'>"
  
Link to link to

Looks like "MyLink" 
When you want to link to an URL outside your own pages it must be "javascript:top.document.location.href='OutsideLink';"
In fact with the help of javascript: you can start a whole script when the element is clicked. "javascript:{your script; another function;}"
  
No of sub elements 
Number- The number of sub elements of this element in the next level.
  
Element height 
Number- The pixelheight of the element.
