I created an Xerte example with a possibility to have a poll by using Mentimeter.
iris.12change.eu/play.php?template_id=141
A great way to interact with your users.
How to? Make a poll in Mentimeter, start the poll and tick the 'share' link. You find a couple of html codes here.
Copy the code below the text 'Share the result on your blog or website' in two Xerte screens. This is the code to show the answers. Change the link in this code in your first screen (it begins with src="https) with the first HTML-code (Use this link to let users vote) .
Have fun
