A custom selectable control that can be used to control areas that can be
expanded or collapsed. The control control can be toggled between selected
and deselected state with a mouse or by pressing 'Enter' while the control
has focus.
The control is rendered as box with a '+' or '-' sign, depending on the
expansion state. Focus indication is rendered around the box when the
control has keyboard focus.
