Great examples of dynamic actions in (dare I say) action.

The fact that dynamic actions can be built without writing Javascript enables application developers to produce very professional looking applications without a lot of work.

I'm impressed!

I've been asking on how to perform dynamic actions on the items in the discussion forum, but everyone suggested to do it using javascript which I don't know how to do it. And I do know that Apex has the ability to perform almost all kinds of features seamlessly. And afte I find this particular OBE, I learned how to perform my required actions(enable/disable/hide) on the items dynamically.
