答案 0 :(得分：0)
我发现您错过了开头<nav>标记，该标记应如下所示：
<nav class="navbar navbar-default">
关于悬停，您可以使用纯CSS hover：
.nav li.dropdown:hover>ul.dropdown-menu {
display: block;
}
请参阅下面的工作代码：
＆＃13;
＆＃13;
＆＃13;
＆＃13;
.marginBottom-0 {
margin-bottom: 0;
}
.dropdown-submenu {
position: relative;
}
.dropdown-submenu>.dropdown-menu {
top: 0;
left: 100%;
margin-top: -6px;
margin-left: -1px;
-webkit-border-radius: 0 6px 6px 6px;
-moz-border-radius: 0 6px 6px 6px;
border-radius: 0 6px 6px 6px;
}
.dropdown-submenu>a:after {
display: block;
content: " ";
float: right;
width: 0;
height: 0;
border-color: transparent;
border-style: solid;
border-width: 5px 0 5px 5px;
border-left-color: #cccccc;
margin-top: 5px;

}
