           NOW HOW CAN YOU CUSTOMIZE

Here normal ul and li rules are applied
To change background simply change background: #414141;
Replace every # with your own link
To create a drop down menu inside a Main Menu link simple add to it a rel attribute like rel="ddsubmenu1 Change the drop down number accordingly
