Hope someone can help me with this.
I'm using superfish with the supersubs plugin.
------------------------- Aim -------------------------
To apply a width to a div that contains the menu ul so it can be
centered using css (auto margins).
------------------------- Method -------------------------
Added some code tp superfish.js to get the width of the ul (adding
together widths of each li) which then applies that result to the div.
------------------------- Problem -------------------------
Its working up to a point. A value is returned but it seems to be too
small, causing the menu to run over two lines.
-------------------------Edited Superfish Code
-------------------------
