You're welcome Enjoy!
Sorry, how can I make that the invisible panel doesn´t go out of the layout limits in the x-direction? (The scrolling is only in the y-direction)
I´ve tried making the panel solid and putting solid objects on the left and on the right side, but it didn´t work. I also tried comparing the X of the invisible panel, and if it was not equal to 0 it had to set its X to 0. This did almost work, the problem is everything moves outside the layout (when dragging) and once you finish dragging, it jumps to the correct position.
Once again, thank you
