Magento 1.9.3 Dropdown Menu

Hi there, Please read full project specification and view files before applying. We have a website which runs Magento 1.9.3 and we require the navigation menu to be modified so it has multiple dropdown menus. Currently the menu is built using Ultra Mega Menu (see screenshots) and the menu does have a dropdown at the moment but we require all the menu navigation names and categories to be changed. You can see the new menu attached under design '[login to view URL]' which displays the first dropdown (this is just for visual purposes, there will be more dropdowns - see the XLS file for all dropdown items). We have set up all the categories within the Magento admin (see screenshot) we require these to be set up in Magento so we have the ability to add / remove and rename the menu items in the future. I am attaching the current code for the menu which is attached as a file '[login to view URL]' we believe this will need editing to be more effective. We also want to easily edit the menu and sub-menu items as I mentioned from the Magento admin. Also I mention we have set up all the categories in the Magento admin - there are more categories than in the menu but these can just be hidden. I'm attaching the new navigation menu design along with the XLS file which shows all the categories and dropdown items. Hopefully this is straight forward, we are happy to answer any questions. We would also like some help if needed when we put these changes live. Please see all attached files which should help give you an exact idea of what we require. The deadline for this is 2-3 days so please bare this in mind.
