How to make jQuery FAQ plugin open we work on projects we need this functionality we can also use this as a accordion plugin.

(function ($) {
    $.fn.faq = function(objOptions) {
        var defaults = {
                speed: 1000,
                remaningClose: false,
                faqnumber: false
            },
            options = $.extend(defaults, objOptions);
        $(".toggleDiv").each(function(index) {
            $(this).slideUp();
			 index += 1;
			 if(options.faqnumber === index){ 
			 $(this).slideDown(0);
			 }
        }), $(this).click(function() {
            if(options.remaningClose){
				$(this).next().slideDown().siblings(".toggleDiv").slideUp();
			} else {
				$(this).next().slideToggle(options.speed);
				}
        });
    };
})(jQuery);

Keep the structure like i have used below here showhide class is following the next element with toggleDiv class just include jquery library and plugin file and use this plugin in your project.

<script type="text/javascript">
	$('dd:first').show().siblings('dd').hide();
	$('dt').on('mouseenter', function(){
		$(this).next().slideDown().siblings('dd').slideUp();
	})
</script>

<div  id="accordHolder">
