Need help with some settings

Hi!
Just install your plugin wp-testing.

How can i set the plugin for creating the same layout with pages (embeded pagination) like here

This website uses your plugin also. And when you choose variant of answer it puts in to the question automatically.
How can i do this?

Thx, Max.
