Changing the jQuery in theme Epira

Hi,
Now i have tried serveral times to get help from Kopatheme after i buy one of there premium themes, but no help to get there, so now i hope someone here can help instead.

I used Epira theme which provide some shortcodes to use for posts, one of them is Accordion, which i want to use.
But for now people need to click on each Accordion for open, instead i want to have all open, when people come to the post.

I have try to find out where to change, but this is a little difficult to find out where they have placed this in theme, but in a javascript file i found following code:

Query(document).ready(function() {
    var acc_wrapper=jQuery('.acc-wrapper');
    if (acc_wrapper.length >0)
    {

        jQuery('.acc-wrapper .accordion-container').hide();
        jQuery.each(acc_wrapper, function(index, item){
            jQuery(this).find(jQuery('.accordion-title')).first().addClass('active').next().show();

        });

        jQuery('.accordion-title').on('click', function(e) {
            kopa_accordion_click(jQuery(this));
            e.preventDefault();
        });

        var titles = jQuery('.accordion-title');

        jQuery.each(titles,function(){
            kopa_accordion_click(jQuery(this));
        });
    }
});

function kopa_accordion_click (obj) {
    if( obj.next().is(':hidden') ) {
        obj.parent().find(jQuery('.active')).removeClass('active').next().slideUp(300);
        obj.toggleClass('active').next().slideDown(300);

    }
jQuery('.accordion-title span').html('+');
    if (obj.hasClass('active')) {
        obj.find('span').html('-');
    }
}

So now i want to know if that code can be changed, so all accordions is open as default, and then what code should i use instead?
