I had to do some tweaking on my Superfish menus today and what I have discovered is that if you are going to use Superfish, get ready to use Firebug and edit the CSS files.
Today I had to make (what I thought was) a really basic change. my drop downs weren’t wide enough for the submenus. i figured that there must be a setting for this but couldn’t find one. So I did some reading and found that to make a change as basic as this, I had to add some css. Not a big deal, but a little surprising.
