This is my first time here on stackoverflow. I have a doubt. I marked some markers on my map (I used OpenStreetMap). On each marker I put a drop-down menu with choices. Based on these choices, the color of the marker must change.
For example: if choice 1 is clicked, then the marker must be green.
I've tried multiple things but I can't seem to get out of it. Could you give me a hand?
i tried to wrote the code, but the website doesn't let me to put it
P.S. I have declared the marker like that
