Hi,<br>
<br>
You might be interested in this unofficial ux I've been working on :<br>
<a class="moz-txt-link-freetext" href="http://dev.geoext.org/sandbox/mapgears/geoext.ux/ux/LayerTreeBuilder/examples/tree-builder.html">http://dev.geoext.org/sandbox/mapgears/geoext.ux/ux/LayerTreeBuilder/examples/tree-builder.html</a><br>
<br>
It's basically a tree panel automatically built from the
OpenLayers.Layer objects you add to your map. It checks for the
"group" property and create the according directories for you.<br>
<br>
As I said, it's not official, but it's a nice way to easilly setup a
layertree without having to know much about the GeoExt components
creating it.<br>
<br>
