Three state checkboxes define the peculiar behavior of a checkbox tree, namely:

• When the user checks/unchecks a parent node - this parent node and all its child nodes (of each nesting level) are checked/unchecked;
• When the user checks/unchecks a child node - this only node is checked/unchecked.
