Cool Jachym.
that's a good idea.
It can even represent the complete structure of a WMS GetCapabilites
(read: WMS Manager [1]).
At the code sprint in Victoria, we where talking with Chris about the
possibility to add few features to LayerSwticher. This could be one.
other possible attribute wired features:
- "buttonDropLayer" : true //activate a button to let the user drop the
layer from map and layerSwitcher
- "buttonZoom2Extent" : true //show a button to zoom to layer extent
- "buttonOpacity" : true //show two buttons change layer opacity
- "buttonMoveLayer" : true //show two buttons to move layers up or down
in the overlay list (this could collide with your structure)
this are the buttons that could apply to all type of layers.
button could be just a div where all styles are defined inside the CSS.
if you and others agree we can expand your Ticket or make another that
can manage all points. Or make a lots of tickets...
ciao
Lorenzo
ps: btw, your patch doesn't work on Safari 2.
