How to open the menu automatically?

Hi :)

I'm using http://docs.jquery.com/UI/Accordion

After opening the menu, I can click links to other pages.


These new pages, I want a BACK button to return to the menu page with the same open.


How?

Look1: http://www.delfa.333interativa.com.br/produtos/

Look2: http://www.delfa.333interativa.com.br/produtos/lancamento-conceito-fit/d3800/

Look2 goback Look1, and menu open in Look1.
