adding a tooltip for each option item in drop down menu

[maria_megha]

I have a scenario where I show a drop-down-with-few-items in a JSP page, to the user.
The length of few options in the drop down is greater than that of the drop down's, hence our requirement is to show the hovered (not selected) option as tooltip for user's convenience. I cannot use the title attribute option as its not compatible with my web browser
