PowerApps - Text Box Auto Height

How to create multi-line text fields in PowerApps which dynamically grow in height as the user types and are capped at a maximum height value. This allows for a large amount of text to be seen on a form, without taking up too much room.

Hi Zach, thank you for this great little idea. One slight problem that I have noticed is that if when you are entering text you press return the box does not change size until you have actually typed text. So the scroll bar appears before the maximum size of the box has been reached? Not sure how to tweak. Thanks

This is what power apps is all about 🤣 Brilliant trick! Thanks for sharing your mastery of the power apps.

As of today (28 Mar 2021) the container flag is now under "Preview features" as opposed to "Experimental Features" and appears to be on by default. Just an FYI for future googlers.
