Then create a script like this…

function JumpToIt(list){  
var selection = list.options[list.selectedIndex].value;  
location.href = “/controller/action/” + selection; // here  
selection acts as params  
}

where you have to call the function in onChange  
… :onChange =\> ‘Jumpto(this);’

Regards.
