I'm having a question about where to start. I have a project that presets a schedule in which this calendar has a table with several squares and presiso change the color of that squares with some colors corresponding to a status and presiso to return this status back to the changed bank I thought of doing where the user clicks on the square opens a color palette with the color change and each color is related to a status but I do not know how to start
the calendar is the same as the image below it is in excel I want to change this in there code in web
