I needed a multilevel dropdown menu in css. I couldn't find an error-free menu that I searched. Then I created a menu instance using the Css hover transition effect.I hope it will be useful for users.
#AnaMenu {
width: 920px; /* Menu width */
height: 30px; /* Menu height */
position: relative;
background: #0080ff;
margin:0 0 0 -30px;
padding: 10px 0 0 15px;
border: 0;
}
#nav { display:block;background:transparent;
margin:0;padding: 0;border: 0 }
#nav ul { float: none; display:block;
height:35px;
margin:16px 0 0 0;border:0;
padding: 15px 0 3px 0;
overflow: visible;
}
#nav ul li{border:0;}
#nav li a, #nav li a:link, #nav li a:visited {height:23px;
-webkit-transition: background-color 1s ease-out;
-moz-transition: background-color 1s ease-out;
-o-transition: background-color 1s ease-out;
transition: background-color 1s ease-out;
color: #fff; /* Change colour of link */
display: block;border:0;border-right:1px solid #efefef;text-decoration:none;
margin: 0;letter-spacing:0.6px;
padding: 2px 10px 2px 10px;
}
#nav li a:hover, #nav li a:active {
color: #fff;
margin: 0;background:#6ab5ff;border:0;
padding: 2px 10px 2px 10px;
}
#nav li li a, #nav li li a:link, #nav li li a:visited {

width: 200px;
color: #05429b; /* Link text color */
float: none;
margin: 0;border-bottom:1px solid #9be6e9;
padding: 8px 15px;
}
#nav li li a:hover, #nav li li a:active {
background: #2793ff; /* Mouse hover color */
color: #fff;
padding: 8px 15px;border:0 ;text-decoration:none}
#nav li {float: none; display: inline-block;margin: 0; padding: 0; border: 0 }
#nav li ul { z-index: 9999; position: absolute; left: -999em; height: auto; width: 200px; margin: 0; padding: 0;background:transparent}
#nav li ul a { width: 170px;border:0;text-decoration:none;font-size:14px }
#nav li ul ul { margin: -40px 0 0 230px }
#nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul {left: -999em; }
#nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: auto; }
#nav li:hover, #nav li.sfhover {position: static;}
