Add feature to save layout in an existing code. The code is to design seating chart but it doesn't have a feature to save that layout so you need to add that feature so that the saved layout can be used in other pages.
Attaching the code, have a look and bid only if you can do it.
Serous bidders only, implement the feature and take your money.
