[Users] Grouping layers in GeoExt2

[Hari Pradhan]

Hello list,

I want to group layers using GeoExt2 as in the link "
http://api.geoext.org/1.1/examples/tree.html" where tasmania layers are
grouped together. The link "
http://geoext.github.io/geoext2/examples/tree/tree.html" provides an
example of this kind of layer tree and is similar to that of v1.1. But it
does not implement grouping the layers.

Can anyone provide me some code snippets for grouping the layers using
GeoExt2?

Thanks,
Hari
