Thank you this reply. Your application is amazing.
I forgot to mention that I would like to customize switcher layers with ol3js. Is it possible?

1) I have several layers in a layer switcher. I would like to attach custom behavior to the layers
- attach an URL to each of them
- show a tip while mousing over
- etc.

How should I proceed

2) How can I have two or three different layer switchers and control which layer goes in each switcher?

I would strongly consider looking at using GeoExt on top OL and using the layer tree. (Example at
http://data.gns.cri.nz/dataportal/ - free registration required but then look at the interactive maps).
