I am attempting to build a custom icon-based dropdown datepicker. The datepicker itself already exists, courtesy of Harmonium. My aim is to have an icon represent the datepicker; upon clicking, the actual datepicker appears, allowing the user to select a date. I assume the best way to implement this is via React, so I tagged react here as well. I am learning both languages as I go, so forgive me if I speak incorrectly about a thing. I legitimately don’t even know where to begin.
