Jqueryui question, multiple instances

Somewhat new to jquery, i was wondering about placing multiple
instances of the same object in a document. I am trying to create a
list of Dialogs using jquieryui.
I currently have one arranged in an accordion menu, but when it try to
duplicate and place another, it overwrites the previous one despite
changing the div id. If anyone has any solutions to this i would
appreciate it.
