One example of such customization is the ability to change the Map marker icon. 

I would like to be able to enable and disable the mouse wheel zoom. 

I want to easily draw lines and polygons on the map. 

The event would fire when the map viewport has moved.

The event would fire when the map zoom level has changed.

ADMIN EDIT: The new zoom level should be accessible in the event handler.

We are using the Map UI Component, where we are allowing a user to enter two points onto the map. Using the map component, is there a way to find a route between these two points as well as find out the distance of that route?

I need to allow users to position a map marker on the map. As such, I need them to be able to drag the marker and/or map but I don't see any drag events documented.

How do I support user marker positioning with interactions like a drag, drop, click, etc.?

Here is our scenario. The use case is for servicing automobile breakdowns. We use the browser to guess the user's location but it may not be correct, either by a little or a lot:

1. The map is initialized with the current device location.
2. The user is asked to confirm the location or reposition the "me marker" to locate the actual position of their vehicle.
3. The user can drag their marker to the actual location.
4. The app records the latitude and longitude of the dropped marker.

We expect users to be on small format devices for this, and precise location data is critical (e.g. on the freeway or a road going under the freeway).

Is it possible to use custom icons for the map marker?
