While Tersus mobile elements make some use of jQuery, there's no straightforward way to implement jQuery features which have not been explicitly included in one of the templates.
Your best bet would be to model similar behavior using the existing mobile templates (List etc.), and controlling them via visibility (<Visible> boolean element), and use CSS to refine the UI. See http://www.tersus.com/#Tag=CSS for some details on how to use CSS in Tersus.
