How to make bootstrap dropdown appear on hover instead of click?

You can use the below jQuery code to show dropdown on hover (Bootstrap 3.0):

$(document).ready(function(){
    $('ul.nav li.dropdown').hover(function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(200);
    }, function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(200);
    });  
});
