I have a fully functioning map using the API v3 with markers placed as a result of database searches, and info windows that pop up correctly. So far, so good.
What I would like to do is to allow the user to place a marker on the map manually, i.e by dragging and dropping a placemark in exactly the same way as google "My Maps" uses to build a map or by clicking on the map.
There are several reasons for doing this, but one is that I would like the user to easily identify a centre point of interest so that I can filter searches within a radius of this point.
I would have thought that this option would be useful to others.
Maybe I am using the wrong search terms for this, and the terms "marker" and "placemark" seem to be interchangeable, which doesnt help, but I cannot formulate a search which has even shown that anyone else is trying to do this.
