Mega menu rework

I have built an ecommerce store using drupal 7 and a navigation bar that was purchased from code canyon. The site has yet to be transferred to it's proper domain as it still needs finishing. It can be found at: [login to view URL] The menu which is causing me the problem is: [login to view URL] The site displays as I want it to on an iphone and desktop perfectly. One style of menu displays on the iPhone and another style displays for desktop. I am happy with both. The problem I am having is that I would like the menu that displays on the desktop to display for the iPad. Currently when viewed on an iPad it displays the menu style for iPhone. The role of the person awarded this job is to correct how this menu displays. All applicants for this work must have experience with Drupal 7 and a comprehensive understanding of web responsive CSS. The hard part will be going into my CSS not having written it themselves and getting to the bottom of the problem. Look forward to hearing from you.
