Bootstrap 3 dropdown transition

Question

Firstly here\'s the fiddle

Just a regular bootstrap dropdown, I made a few changes to css so that the dropdown appears on hover (instead of click) but how do I want

Answer 1

You can override the default style of display:none with display:block, since you're also using opacity:0 to hide the menu. Give the following CSS a try and see if that accomplishes what you need. I've updated the transition speed to make the effect more apparent.

.dropdown .dropdown-menu{
    display: block;
    opacity: 0;

    -moz-transition:    all 1000ms ease;
    -webkit-transition: all 1000ms ease;
    -o-transition:      all 1000ms ease;
    -ms-transition:     all 1000ms ease;
    transition:         all 1000ms ease;
}
.dropdown:hover .dropdown-menu {
    display: block;
    opacity: 1;
}

Here's a jQuery script that might work as an alternative to hovering over the div (still using the css transition properties for opacity)

$(function(){
  var $menu = $('.dropdown-menu');

  $('.dropdown-toggle').hover(
    function() {
      $menu.css('opacity',1);
    },
    function() {
      $menu.css('opacity',0);
    });
})();
