This actually is not very easy to do. Scrolling the page isn't really something that SmartBuilder pays attention to. There isn't a mechanism for detecting "the user has scrolled down past a certain point". So I'm not really sure how we can simulate this.
We can make things "Float" so that when a user is scrolling, items move along with the viewport (such as making a persistent top or bottom navigation bar that scrolls with the user), but that is generally designed to make a consistent UI, not one that changes behavior.
Perhaps if you do not use fluid scrolling, and instead have a "Scroll Down" button which switches the view, then you actually have an event (the button click) that you can detect, and show/hide the appropriate search bars.
If the website is public-facing you can send us a link to the site you're trying to simulate (either here or via email), and we can see if we have any ideas.
