Use js or jquery to realize the multi-level menu effect of navigation bar most quickly.
I use jquery 1.9. 1 for this code, and the compatibility below ie8 needs to be considered, mainly for the introduction of the code, write less, do more.

<style type="text/css">
.top-nav
{
font-size: 12px;
font-weight: bold;
list-style: none;
}
.top-nav li
{
float: left;
list-style: none;
margin-right: 1px;
}
.top-nav li a
{
line-height: 20px;
text-decoration: none;
background: #DDDDDD;
color: #666666;
display: block;
width: 80px;
text-align: center;
}
.top-nav li a:hover
{
background: #900;
color: #FFF;
}
.top-nav ul
{
list-style: none;
display: none;
width: 80px;
padding: 0;
position: relative;
}
.top-nav li ul li ul
{
position: absolute;
top: 0;
left: 80px;
}
