Share button Question

I was playing around with it, and noticed the button redirected off of the page once used.

While looking through some pages, I've just found one that has text instead of the button (I'd like to know how to do this), has pre-written content for the user (not below the text area like usual, but actually within it, as if they typed it), and displays the final step after completion.

I can show an example page to anyone who thinks they can help me out with this...but yea I just can't get it to work lol.

Thanks

Yeah i saw it too. Wondering if someone cud share it.
