How to make the opportunity to travel across the screen

Help someone who can. I’m doing a play and I have a shop menu in the game where you buy, get new opportunities, but I have almost ends the screen, and make sure that could drag down the screen, I do not know. Help please: how to make in my shop you can hold your finger on the screen and expand this market.

@iceman search for “scroll bar” or something like this on forum. Here we have some code examples!

Hmm maybe @CodeaNoob has this code

If you look up “Scrolling List Demo,” someone put a cool scrolling list up there, or you can use Soda or Cider.
