Expandable scrolling panel
I got a scrolling panel with a couple of objects on it.
Its a text then a video and finaly a arrow pointing downwards.
Now i want the scrolling panel to be filled with more content after the user clicked the arrow. But i can't figure out how to do it or if it's even are possible.
See picture where i try to explain my idea. (As you can see i also want the arrow to vanish)
