None of the ListMorphs in Squeak are (yet) hooked up to the Etoys system.
Initializing them is a little tricky.
LazyListMorph can not be used separately,
PluggableListMorph and subclasses are the ones to look at.

The component system could be used for what you try to achieve but I
think it is broken in the Etoys image.
