There's no built in support for scroll-able textbox or a textarea component for HTML5 Canvas doctypes in Animate.
So, it'll involve a bit of work to emulate it in the way you wish.
One way to set this up is by using Static Text with masking applied on it, and coded to be controlled by a scroller symbol.
Another way is - using DOMElements - which allows linking of any HTML tag/component with your canvas based animation published via Animate. An HTML textarea with fixed width/height set as DOMElement can be overlay-ed on top of the canvas.
Could you maybe elaborate a bit more on how to do that? What are the actions to take? I have little experience with coding.. Is this possible with the action panel ?
I hope to hear from you!
Hey did you figure out how to do this? I need to do the same thing and also have very little coding experience.
