🚀 go-pugleaf

I need to be able to have TreeControl component inside the GridControl
and
each row of the Grid has to be corresponded to appropriate level of the
Tree.

So tree should be expandable as well as grid in which it's situated(in
that case additional rows should be automatically inserted in the Grid).

(I hope behaviour is understandable though it's quite difficult to
describe: From the user point of view Tree should be INSIDE Grid
component).

The question is how to implement it with more elegance and using most of
the benefits
of Model-View architecture? (Really the first question is: IS IT
POSSIBLE to do it
using jbcl components?)

Thanks in advance,
Oleg.
