I found this great link http://jsfiddle.net/ionko22/4sKD3/ regarding collapsible div using CSS. Is there a way to have question 1 always open without clicking on it when you visit the page. And make it collapse when you click on any other questions. Also is there a way to close the div/questions by clicking on itself? I would be very grateful if you can reply to this.

Add this to the CSS to make the first question appear by default:

.faq ul li:first-of-type div {
    display: block;
}

And add this jQuery for toggling:

$(".faq ul li").click(function() {
    if( $( this ).children( "div" ).css( "display" ) == "none" ) {
        $( ".faq ul li div" ).hide();
        $( this ).children( "div" ).show();
    } else {
        $( ".faq ul li div" ).hide();
    }
});
