Creating a "top of page" ???

Creating a "top of page" ???

jquery.accordian.js is what I'm using. I have a list and using the jquery.accordian.js as a verticle set-up, the list expands past the boundaires of the page. Thus resulting in seeing 3/4 of the disappear. How can I get the link within the "accordian" to go back to the top of the page when clicking on the selected link. If this did not make sense let me know. I need help.
