load a functoining dropdown menu in nav menu widget with Megamenu

Hi again, Don't know if this is appropriate to request, but when using MEGAMENU plugin, for the second level menu, I want to have the submenu items collapsed until the menu title is hovered over. To be more specific: my url is http://compassionatehardball.com I am currently using only the nav.menu widget when u hover over "about" in menu bar, it currently display unactionnable yellow menu titles and the submenu elements of each title are already visible. Is there a way to make the Yellow menu title actionable so that hovering over it shows the submenu item? Or is there a widget that can show the full drop down menu in collapsed form until title is clicked? I tried doing it using the Custom_Menu widget, with no success, but that may be my ignorance about how to use that plugin. Many thanks for any code suggestions you might give me.
