Q: Some menu entries may be disabled and clicking on them should produce predefined javascript alert message?
A: To create disabled items you should set "_" symbol in the targetparameter of the menuItems.
If the target is "_" the item is disabled.
You can assign a font color for all disabled items using the following menu parameter:
var fontColorDisabled = "#AAAAAA";
You can write a javascript code instead of an item link:
["item text", "javascript:alert('Hello World')", , , ,"_",]
That's all.

Q: We currentlly have a menu that uses standard html hyperlinks to open a new window with _blank as the target. Unfortunately, the size of the window is controlled by the browser and we want to be able to control it. The only way that we know how to do that is to use the window.open client-side function and pass the window's dimensions. Here is a sample of the code that would do that:
window.open("url","_blank","height=1024,width=768,status=yes,toolbar=no,menubar=no,location=no");
How can we add the javascript code to the dhtml menu vertical instead of a link? Do you have any samples?
A: You can use javascript code within menuItems, for example
Write:
["Test Window","javascript:window.open('http://www.microsoft.com','_blank','height=1024,width=768,status=yes,toolbar=no,menubar=no,location=no');", , ,'Monitor Exceptions' , , '0', '0',,],
