我在导航栏中使用Bootstrap和bootsnip的css http://bootsnipp.com/user/snippets/rVnKg.

这是JSfiddle 链接 – http://jsfiddle.net/ask1987/8xc7fk43/

.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;
    border-radius: 0 6px 6px 6px;
}

.dropdown-submenu:hover>.dropdown-menu {
    display: block;
}

.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: #ccc;
    margin-top: 5px;
    margin-right: -10px;
}

.dropdown-submenu:hover>a:after {
    border-left-color: #fff;
}

.dropdown-submenu.pull-left {
    float: none;
}

.dropdown-submenu.pull-left>.dropdown-menu {
    left: -100%;
    margin-left: 10px;
    -webkit-border-radius: 6px 0 6px 6px;
    -moz-border-radius: 6px 0 6px 6px;
    border-radius: 6px 0 6px 6px;
}

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container-fluid">        
        <div class="collapse navbar-collapse">            
            <ul class="nav navbar-nav navbar-right">                
                <li>
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Menu 1<b class="caret"></b></a>
                    <ul class="dropdown-menu multi-level">
                        <li class="dropdown-submenu">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown</a>
                            <ul class="dropdown-menu">
                                <li><a href="#">ActionActi onActionA ction</a></li>
                            </ul>
                        </li>      
                    </ul>
                </li>
        </div>
    </div>
</div>

问题是当在ul元素上使用Navbar-right类时菜单项溢出.

如果它设置为左,导航栏工作正常.

有人可以帮助解决这个问题吗？
