Thumbnails in Revolution Slider help needed

Hi, pardon me if I ask simple or stupid question. I’m a new here on forum and I recently started to learn wp. I bought one theme and got basic Revolution slider included and I want the slider to show up in a container as a thumbnails slider and when you click on it to open in Full size but I can’t find any tutorial how to do it. I’ve read manual about thumbs but it still didn’t solve my problem. I would appreciate very much if someone could tell me how to do it in Rev Slider. Thank you!
