Iframe without fixed height?

Question

HTML

I need to map an already compiled React app to another React app.
But the problem is that if you display through an iframe, then you get a fixed-width iframe, and if the height of the compiled application is larger than necessary, then scrolling is displayed.
I also need the iframe to not have a clear height, but it adapts to the source.
Is it possible to do so?

Answer 1

Maybe I do not understand something, just setting the width and height to auto will not help?
