To use the expanded popout, make sure you have Holler Box Pro active on your site.
This feature hides content until a button is clicked, for example a form or video.
First, create a new Holler Box, and enter the content you'd like to show before the button is clicked. For example:
"Hey, can I get your opinion on something?"
Enter any other options you'd like, then click the Popout meta box.
Enter the button text, such as "Show Form."
In the editor, add the content you'd like to show when the popout is in the expanded view. For example, a form shortcode, video, or other text/images.
A Gravity Form shortcode with ajax enabled works well here.
