Menu code advice

[Joax]

Can anybody please help me with a JavaScript coding matter, I have a sliding menu which works well and links to the required websites and web pages on my site, the menu is set-up as menus and sub menus, you click on the menu and the sub menu appears from there you can select what you want from the sub menu.



For example you can click on the help menu, and a sub menu appears with web help appears where you can click on to select a web page concerning downloading flash viewers..etc



However, I’m trying to change the code because some of the menus only have one sub-menu, for example I only require one page for the help section, so what I want to do is not have sub menus for some of the menus, I would appreciate any advice on this matter.



I would appreciate any advice on this matter.



Regards,

Sam





THE EXISTING MENU CODE IS AS FOLLOWS: (the ‘0’ are the main menu headings, and the ‘1’ are the sub menus)



//Link[nr] = "position [0 is item/1 is item],Link name,url,target (blank|top|frame_name)"

var Link = new Array();

Link[0] = "0|Help";

Link[1] = "1|Web Site Help|html/webhelp.htm|mainFrame";

Link[2] = "0|About Us";

Link[3] = "1|hello|html/hello.htm|mainFrame";

startup(0);



THE SCRIPT IS AS FOLLOWS:







var height = 20; // height of the menu headers

var iheight = 15; // height of the menu_items



var bgc = "lightyellow" // background color of the item

var tc = "black" // text color of the item
