What is possible with actionable notifications?

With iOS 8 you're able to use actionable notifications. iMessage has an textbox to reply to messages and Mail has two buttons, but what input methods can you put in an actionable notification?

Is it possible to have 5 smaller buttons next to each other so you can present a scale? And can you add a slider (UISlider)?

Does anybody have more information on what is and what isn't possible with actionable notifications?

Any help is welcome. I really need to find some info for my graduation project.

ps. I'm a designer and not a programmer, therefor I can't test it myself or anything.

Thnx
