I am trying to implement accordion in visual force page. And it works fine in salesforce platform. However, if I see the same page in customer portal it doesn't work.
The root cause is showheader. If i say showheader= false, the jquery ui css loads fine. I want showheader to be true. Has anyone faced this issue? 
google CDN works.. however i would like to have a local copy of jquery and css in Salesforce. Kindly help.
