Question

Google Maps

I need a map with the ability to be marked on it by site users, how to do it? Ready-made solutions are of interest, maybe there is some kind of "constructor" of this type from Google, or scripts / plugins are needed for a wordpress site.
That is, the map is loaded, and below the form for "registration" on this map, you can use Yandex and Google maps, it doesn't matter. So that a person can mark where he is, and send some of his data in the form under the map, you can not "auto-add" but so that the info is where he was marked on the map.

Answer 1

You can do it with Yandex.Maps in an evening using the Ya.Maps API

Answer 2

Use leafletjs.com
