Solution

Just Replace Your This CSS

.dropdown:hover  {
  /* Size & position */
    position: absolute;
    display:block;
    top: 100%;
    left: -5px;
    right: 0px;

    /* Styles */
    background: white;
    -webkit-transition: all 0.3s ease-out;
    -moz-transition: all 0.3s ease-out;
    -ms-transition: all 0.3s ease-out;
    -o-transition: all 0.3s ease-out;
    transition: all 0.3s ease-out;
    list-style: none;

    /* Hiding */
    opacity: 0;
    pointer-events: none;
}

To My CSS and Get Result

.wrapper-dropdown-2:hover > .dropdown  {
   position: absolute;
    display:block;
    left: -45px;
       background: white;
      top:24px;
 }

try this

.wrapper-dropdown-2:hover ul{
    display:block;  
}

updated jsFiddle File

also remove .dropdown:hover from your style

You will need to initialize your javascript as well as link to jquery. I see you are using a dropdown from Codrops why dont you just download the source?

You are missing to add hover code to see drop down when hover over. add css for hover.

.wrapper-dropdown-2:hover .dropdown
{
    display:block;
}
