[OpenLayers-Users] How to program to drag markers

[Adam Eskreis]

I believe all openlayers markers have a unique element ID (since they are
after all just DOM elements).  You should be able to get this ID from the
API available to you through the OpenLayers.Marker class.  I would then
attached mousedown and mouseup events to these markers, and use regular
javascript functions to change the positioning (I believe markers use
absolute positioning, so measuring the delta of mouse movements and altering
the left and top css properties should accomplish this).  Then just update
the lonlat of the marker when the mouse is released.

Should work theoretically anyway.
