Two ways to create a scrollable textbox. The first is with a text input, and the second is with a layout and a label.
Text Input
This is the easiest way. Add a text input. Set Editable to FALSE and Multiline to TRUE. The only problem with this method is that Editable only works on IOS and Android. This does not work with web preview or web publishing.
Layout and Label
I would recommend using the text input method if possible, but this is how you set up a layout and label. First, have a label in a container all by itself. Set the label to the setting below, and make sure the container is scrollable.
