Collapse Tree

Clicking this button collapses the datatree (Tree-View) to its minimal size.

Tree collapsed at its minimum:

If you want to collapse the tree but keep one subgroup open, you can do this by clicking/highliting one of the elements in this subgroup and then collapsing the tree:

1) Open tree with 'Crebelley' highlited in group 144

2) Collapsed tree with group 144 still open

The opposite would be to expand the tree.
