Recently I research on how to implement a javascript menu navigation. At the beginning, I was thinking of use library to make one. But there are so many different request coming in until I decided to develop my own javascript menu navigation.
Here is the sample code that I write (3 levels menu navigation):

During testing on this sample code, I find out that IE6 having some different behavior then IE7 & Firefox on onmouseout() function. If possible, avoid to use that function.
