You can choose whether you show one question at a time or all survey questions on the page together. By default LoudHippo will show one question at a time, with a 'Next' button to take the customer to the following question.
Showing one question at a time works better for surveys that contain logic for follow up questions
Navigate to your Survey editor, and the survey panel on the right side of your screen
Under the heading Navigation, scroll down to Survey structure
Select All questions on a single page, then click Save changes
