Create Symfony interface for Drag and Drop screen

I need someone to create the necessary code to make a Drag and Drop screen work as part of a Symfony project. The link below contains a simple demo of the kind of screen the needs to integrated into Symfony: [login to view URL] This project uses the Dragula library to create the screen. The purpose of the page is to assign each occupant to a bed in a room. Each bed can contain 1 or 2 people. There can be multiple rooms and each room can contain one or more beds. You should create a standard Symfony controller, Twig template files and any supporting code to handle dynamically building the screens and collecting the outputs. The inputs to the controller should allow it to dynamically build an "Occupant Bed Assignment" page that consists of the following: - a list of occupants - a list of "room" containers which contain one or more beds It should be possible to tag each room with a name (e.g. "Bedroom 1") that will display with the room container. It should also be possible to tag each bed with a bed type (e.g. "King" or "Single"). When an occupant is moved to a bed, the controller should capture the information. The page outputs captured by the controller will not be tightly coupled to a specific database (we're NOT using Doctrine ORM), but should be designed to interface with any storage method. For test purposes, you can use any storage method. For development purposes, you should create code that is similar in design to the latest Symfony demo project (available from [login to view URL]). Requirements: - code must follow Symfony current "best practices" (see [login to view URL]) - must work with Symfony version 2.8+ - must be mobile-friendly (compatible with Bootstrap) - must support internationalization
