Christopher, Thanks for the reply. That's interesting that there is no way to add in a Legend (right now).
I did mange to get something to appear (by slightly cheating), reload the link . . .. I just added in some HTML to the Title for Line breaks, and Image SRC links. Seemed to work pretty good. But then I noticed that it would be nice to have the Legend graphic disappear when the layer was toggled off. I keep making work for myself. I have no idea what this approach might break along the way. I could expand on this and try to build in a dynamic Legend item I suppose, but it doesn't seem like the right approach to take. I not much at Javascript either. More of an "example tweeker" as far as Javascript goes. I'm doing something really quick and dirty right now. But I suspect that I may be doing more of these in the future. bobb >>> <christopher.schm...@nokia.com> wrote: On Jun 17, 2011, at 5:45 PM, ext Bob Basques wrote: > All, > > Playing around with my first (official) Openlayers Viewer. > http://pwultra5.ci.stpaul.mn.us/ol/ol.03.html > > A couple of questions: > > 1.)

You'll probably need to write your own LayerSwitcher. We don't have any supported way of doing this that I'm aware of; there are a few hacks out there that people have done, but I don't think we've integrated them into the LayerSwitcher in trunk. > 2.)
