superfish menu plugin and submenus always opened

superfish menu plugin and submenus always opened

Hi all,
I'm using this jquery plugin:
http://users.tpg.com.au/j_birch/plugins/superfish/#examples
The "nav-bar style".

I would like that submenus remains open until user pass mouse over another FIRST-item menu, like this site menu:
http://lastampa.it/redazione/default.asp

For now, if I move mouse out of menu, the sublevels disappears after few seconds.
I saw that Superfish has these customizable function:

onInit:        function(){},       // callback function fires once Superfish is initialised – 'this' is the containing ul 
onBeforeShow:  function(){},       // callback function fires just before reveal animation begins – 'this' is the ul about to open 
onShow:        function(){},       // callback function fires once reveal animation completed – 'this' is the opened ul 
onHide:        function(){}        // callback function fires after a sub-menu has closed – 'this' is the ul that just closed 


Thanks in advance for the help!
Francesco
