[OpenLayers-Users] Is it possible to add a legend to the layer switcher

[Marc Jansen]

Hi David,

AFAIK you cannot embed a legend within the LayerSwitcher using 
OpenLayers without changing the LayerSwitcherControl itself. There is no 
API-method/variable to add legend images to the LayerSwitcher. Of course 
you can have a look at the source of the URL you provided:

In the file
http://www.microimages.com/ogc/newtntmap/openlayers/lib/OpenLayers.js
from line 12374 the changed LayerSwitcher-Control is defined. Looks as 
if they are reading a 'legendImg'-Property of a layer and add an 
<img>-Tag to the LayerSwitcher if that is set (line 12522).

Hope that helps.

Regards,
Marc
