Fix mymenu dynamic drop down menu mess by cheapestandbest

This is a project I posted a couple of weeks ago on GAF, another service provider from here worked on the project, but he has stopped giving support since he was paid, so I need someone to complete the project please. The main problem is the menu has white background, but in Firefox, the menu is see through and looks a mess. I need someone to fix this and to also check the menu displays ok in all other browsers and is ligned up ok, and to make any nessesarry changes if needed. Im not interested in hiring cheapestandbest and again, so dont bother bidding on this project.
