invoke the mouse over action on a widget using javascript?

[HowardA]

I wanted to see if I can make the mouse over action occur on a menu widget when I mouseover an image.
If there's a way to invoke the action on the menu widget using java script I assumed I could include the code in the onmouseover of an image widget.

End result I'm trying to accomplish is using the dropdown/multi-levels of the menu widget in a toolbar. but, instead of "text" appearing for the top menu level, I wanted an icon. SO, I thought perhaps I could overlay the menu widget with an image/icon, when the user hovers over or clicks the icon, it would act like they were pressing / hovering over the menu widget behind the image.

Thanks
