Hi Guys,
I´m working with this piece of code:
        $(this).toggle( function() {
            $(this).children().slideToggle('fast', function()
{ $.cookie('_wp_el_' + i, i, { expires: 30, path: '/', domain:
'leandrovieira.com' }); });
        }, function() {
            $(this).children().slideToggle('fast', function()
{ $.cookie('_wp_el_' + i, null, { expires: 30, path: '/', domain:
'leandrovieira.com' }); });
        });
The cookie isn´t dele anyway. There´s something wrong?
Regards
