Superfish menu opens on click rather than on hover

I couldn't find anything online that worked for changing the Superfish menu to open on click rather than on hover. Here it is:

Changing this line (line 21, over function):

$$.showSuperfishUl().siblings().hideSuperfishUl();

To this:

$$.click(function(){$(this).showSuperfishUl().siblings().hideSuperfishUl();});
