[jQuery] [Superfish] How to make secondary menu (i.e. the hover menu) horizontal instead of vertical

[Stephen]

Hi,

I'm working with Superfish drop down menu which implements JQuery.
Have it installed on Joomla 1.5.7 and am working on making the second-
level menu horizontal.  Right now hovering over a menu item with child
items produces a vertical list.. I've tried to manipulate the CSS so
that the <li> child items have {display:inline; list-style-type:none;}
but it's not working.

Not sure if I'm applying to the right CSS class or if CSS is the
answer.

Any help would be appreciated.
