In order to have a function activated onMouseOver or onMouseOut you will need to include your function name within the aI text string of a menu item as in the following sample:.

aI("text=Sample Item 1;onfunction=yourfunction('param1','param2')");

off function is the same but you change the onfunction to offfunction in the above aI text string. In order to have both onMouseOver and onMouseOut your menu item must look like this:

aI("text=Sample Item 1;onfunction=youronfunction('param1','param2');offfunction=youronfunction('param3');");

If you need to have your menu activate a function onClick you would use a menuitem like this:

aI("text=Sample Item 1;url=javascript:alert('Displaying an alert box');");

You can also include onMouseOut and onMouseOver functions to the above sample
