Need a simple FullCalendar.io Solution#2

I need some help with [login to view URL], jQuery and CSS. The final result will be added to my existing code by me, so I only need someone to fix these specific issues: I use the FullCalendar in Week mode, and code should be written in jQuery with the latest [login to view URL] Issues that need to be solved: 1. I use the BusinessHours option to add working hours, I want all times that is not within BusinessHour to be greyed out (with a css class). 2. A business day is e.g from 0800 to 1600. With a lunch breaks from 1100-1130 and from 1400-1430. These breaks should also be greyed out (like in #1). 3. A function to check if a dropped Event is outside of BusinessHour/inside lunchbreak, returning simple True/ false.
