Can I add content outside mobile phone screen?

Klas Hermodsson shared this question 4 years ago

I am prototyping a mobile app using the iphone 5s template. For some parts of the UI flow I need to have some trigger that allows a popup to be displayed. I was thinking of having a button to the right of the phone form factor that is a button and explanation.

It seems Justinmind just allows content on the phone display itself even though the simulator has lots of space next to the phone.

Is it possible to do what I want?

If not, any ideas of how to have user triggers that do not clutter the on screen UI somehow?
