this is the prototype that i work out : prototype

the original script is very short and simple, i just enhance it and added transparent png (try products > agriculture > blower )
IE < 7 does nt suport transparent png, must use javascript to fix this problem.
i combine alot of script to work out this menu, of cause some modification

from the research, only 5 - 10 % of user will purposely disable java script and the major reason behind it is for the security purpose.

sure : file1,
file2,css

yaya lets firefox, ie suck

ya, now adays must work with differ browser, mine one so far no problem in firefox and IE, perhaps others browser too, but the main concern is this two major browser...some script work in IE but not firefox, some are vice versa.
