Suppose you have a container morph, which contents is entirely depends
on menu selection.
And you have say, a 3 sets of controls which you want to show
depending on current selection.
Create 3 morphs , add all submorphs to them, as appropriate.
Then , based on selection you can do:
container addMorph: (morphGroups at: x).

and when selection changes:
container removeAllSubMorphs (not sure if this method exists)
container addMorph: (morphGroups at: y).

where morphGroups is collection containing a morphs each holding
submorphs you need to display for given selection.
