The ISmartTagAction interface has an ActionSets property from which you can return action sets related to the smart tag action. I thought this might function like a submenu. However, if any action sets are returned, nothing happens. All you see is the display text for the parent item but no submenu indicator. Clicking on it does nothing either even if you add code to the Invoke member for the parent item.
Setting a breakpoint in the property shows that it does get called. Is this property broken, not used, or am I misunderstanding how its supposed to be used? Is there a way to get the effect of a sub-menu on a smart tag action set item?
