bootstrap 3 navbar active li background -


i have bootstrap navbar in this fiddle , dropdown visible on hover mouse as

 $('.navbar .dropdown').hover(function () {         $(this).find('.dropdown-menu').first().stop(true, true).slidedown(300);     }, function () {         $(this).find('.dropdown-menu').first().stop(true, true).slideup(180)     });

but how make parent li background still active when mouseover down dropdown menu similar 1 without sliding.

you can add class open on-hover , remove on mouse leave. see below example,

  $(document).ready(function() {      $('.navbar .dropdown').hover(function() {          $(this).addclass('open');        },        function() {          $(this).removeclass('open');        });    });
