and try, in hover mouse to: sign in open drop down not work ! cant work js. because have problem 1.8.2, think can find solution css

just replace css

.dropdown:hover  {   /* size & position */     position: absolute;     display:block;     top: 100%;     left: -5px;     right: 0px;      /* styles */     background: white;     -webkit-transition: 0.3s ease-out;     -moz-transition: 0.3s ease-out;     -ms-transition: 0.3s ease-out;     -o-transition: 0.3s ease-out;     transition: 0.3s ease-out;     list-style: none;      /* hiding */     opacity: 0;     pointer-events: none; }

to css , result

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