Update an existing Java Script/HTML/CSS module that allows for drag&drop of tasks (represented by rectangular boxes) on a timetable (represented by a time grid with 15 minutes resolution). Each task has a pre-determined 1. Length, 2. Window of execution and 3. Address (all that is pulled from our backed). The Java script allows to A) visualize all tasks in the unassigned tasks section where their width is determined by the duration of the task and B) know the column and the raw where each task is dropped depending on their duration in minutes. A detailed sample and additional info will be provided to shortlisted candidates.
You MUST use object-oriented programming, JQuery and Bootstrap. You'll need to make separate components for Tasks, Users, Schedule and any other substantial component (for example class ListHoursWidget, etc.).
