Horizontal Sub Menu

Hi All

First post - so be gentle.

My CSS is pretty limited and I'm stuck with a current problem - I've already followed a few tutorials from Google and spoke to the creators of the theme (who wanted money to do the alterations themselves):

I'm converting a vertical dropdown menu on a WordPress site to a horizontal submenu, but I can't get the submenu to sit in the right place:

The horizontal submenu can be seen at - http://www.test.thebreaker.co.uk/
The original vertical submenu can be seen at - http://www.thebreaker.co.uk/

I would like it so all the submenu always sit where the 'News' one does - flush with the left hand side of the parent menu.

Any ideas on how to do this? Not even sure if the original code I have put in is heading in the right direction?

thanks in advance

Rob
