ThemeForest - ZAPanel - Most Complete and Clean BS3 Admin Panel
Featuring 28 fully functional elements pages, it is the largest and most powerful Admin Panel you would have seen ever. Built on the latest version of Bootstrap (v3.0.1), it is super responsive. Usually, in the ordinary admin panels, there are just 15 elements out of which only 7 or 8 are found to be functional, while the remaining are static. So, if you are dealing with the business of website hosting and want to manage your project effectively, the ZAPanel HTML template offers you a lot more than what you want!
