Making an Accordion List occupy a Page into 3 columns

Making an Accordion List occupy a Page into 3 columns

  
   I have an accordion list and I want to make it so that if the list will occupy the whole page but is divided into 3 columns. How can this be done? Since the current design is only occupying 1 column in the web page.


I am not sure I understand your issue?

Change the outerdiv to "full width" ?
