making code work on wpbakery

Code attached to this project is not running properly on WordPress. I inserted it in raw html element via WPBarkey: the slots are not loading content from database and the whole code is conflicting and overlapping with site elements (menu, sidebar, footer, ...). Here's the page with the code: [login to view URL] Here's the original page and how it should work: [login to view URL] When you start typing the town name in the first slot (for example "Roma") it starts loading towns and suggest intuitive content. After selecting town from the scroll menu in the first slot, same thing for address in second slot (for example "via tiburtina"); after selecting address from the scroll menu in the second slot, same thing for number (for example "15"). After selecting the number from the scroll menu, the submit button ("CERCA") is enabled. It shouldn't be hard, I'm just missing where the mistake is. Very short deadline, very low budget. $20
