adding jquery only to pages that use a specific template

Hi all, I have some pages that use template with a sidebar. On that sidebar I use the widget “Pages” with exclusions in order to show a mini navigation menu. I need to modify this menu a bit so that it has collapsible items. I already solved the link disabling for the “current page” link thru css. But to have parent list items collapse etc javascript is needed. How can I only add a jquery script to those pages that use this template and sidebar? Thanks
