Viewer scale

I still want to keep the scale.

What you did, loses the scale.

But I do see a solution using your method.

Can you give me two buttons at the bottom of the rendering, to increase or decrease the height of the rendering?

This will allow the user to adjust the height to show everything.

This also increases engagement on the page.

This is a basic javascript question not specific to Super-Resume.  If you need help with this, you can hire our consultant.
