Header Navigation Sliding Field

Does the pro version allow for the sliding field form on the top bar navigation like is shown on your site.
Before using your plugin I tried to code the search field on the secondary top navigation bar but couldn’t align the search field on my sidebar search. When I use 100% width on the sidebar the header search places itself on a separate line.
When I override WP search with yours it places itself on a separate line and the field is as wide as all the links. (secondary nav top)
So I’m using the WP search for header and your search for sidebar. If your pro version allows a sliding search field like what you have on your site then I believe my client will buy it.
Or is there another solution or code I can use.

Thank you
