Needing help with adding placemarker on google map
I have some working code for 1 part of this project I'm working on but I also want to be able to add multiple markers on a map as well. I have included my working code but it doesn't seem to be working. I pieced it together from two working examples.

Just to clarify, do you have a preset list of marker points or are you looking to search and add repeatedly?
ASKER
thx! I'm eventually wanting to save the dropped points so that if the page is reloaded it will output the same markers. I was just getting this worked out first.

sorry for the lack of communication. The entire scope is this page is to serve two functions.
1. Searching for places and adding a marker/location to a list below the map when clicking a button "ADD LOCATION" inside the infowindow (info window being the little tooltip area above the marker when clicked if that wasn't clear).
2. Dropping a marker and having the same functionality with having a "ADD LOCATION" inside the info window.
Both functions would populate two separate lists after the user has clicked "ADD LOCATION" on each type of function above. And of course I would like to populate those markers eventually when the page is reloaded.
Thanks for the help again, I appreciate it. And I'm not suggesting that this entire scope be solved but I'm just trying to get the dropped markers to populate on the map first.

Figured it out on my own. Thx for trying.
