it going ı need write jquery or js think how can reach each li class ? 

var activeurl = window.location.pathname;     $('a[href="' + activeurl + '"]').parent('li').addclass('active');     $('a[href="' + activeurl + '"]').parent('li').parent('ul').parent('li').addclass('active');

these codes solved problem.
