A collapsable panel is a container with an embedded button-like control which can be
used by the user to collapse or expand the pane's contents.
+Note that because of its nature of control which can dynamically (and drastically)
+change its size at run-time under user-input, when putting wxCollapsiblePane inside
+a \helpref{wxSizer}{wxsizer} you should be careful to add it with a proportion value
+of zero; this is because otherwise all other windows with non-null proportion values
+would automatically get resized each time the user expands or collaps the pane window.
+
+It is only available if \texttt{wxUSE\_COLLPANE} is set to $1$ (the default).
