onMousein and onMouseOut in a Menu

onMousein and onMouseOut in a Menu

How can I do that in my example ( http://jsfiddle.net/samuvk/sMqKA/14/)    Place1 and Place2 only appear when sitting the mouse over the object "Places"?

If possible I would like to display like this:

Home  Places 
    Place1  Place2

Instead of 

Home    Places
            Place1
            Place2

Thank you so much
