How can I make this personalized accordion load closed?

How can I make this personalized accordion load closed?

This is the current code that I have for my accordion script:

$(function(){

    $('#q-and-a li a').each(function(){
        $(this).click(function(){
            $(this).siblings('div').slideToggle(300);            
        });        
    });                
 
}};


I was wondering how this could make the page load on opening. I know that you need 
{ active: false, collapsible: true }, but the problem is I dont know where in the script it would go. Any help would be appreciated, thank you so much!
