You can drag a “Text” widget there, and then add the content inside of that widget. Genesis Child themes don’t come with Shortcodes (it’s not good practice, see here – http://justintadlock.com/archives/2011/05/02/dealing-with-shortcode-madness ). What they’ve done here is added the html that you can use inside of the widget areas. The html used in the demo can be found at the top of the Epik Forum – https://appfinite.com/forum/epik-theme-support/ (they are the yellow highlighted sticky posts)
