Question

菜单与其他菜单重叠。当您单击第一个菜单“关于我们”时，它会打开。但是当您点击“产品”时，“关于我们”不会关闭，因此“产品”菜单与“关于我们”菜单重叠。

HTML

<body>
<nav>
   <ul class="nav">
        <li><a href="#"></a></li>
        <li class="menuabout"><a>About</a>
             <ul class="subnav01 clearfix">
                  <li><a href="#">About One</a></li>
                  <li><a href="#">About Two</a></li>
                  <li><a href="#">About Three</a></li>

Answer 1

你可以尝试这样的事情。我已将所有菜单元素的类更改为menu，因此您可以为所有菜单元素使用一个函数

JSFIDDLE

jQuery(document).ready(function($){
    $(".menu").on("click", function(){
        deactivateAll(this);
        toggle(this);
    });

    function deactivateAll(current) {
        $( "li" ).each(function( index, elem ){
            if (elem != current && $(elem).hasClass("active")) {
                toggle(elem);
            }
        });
    }

    function toggle(elem) {
        $(elem).find("ul").toggle ("slide", {direction: "right"}, "slow");
        $(elem).toggleClass("active");
    }
});

这有效：（Fiddle）

jQuery(document).ready(function($){
    $(".menuabout").on("click", function(){
        reset();
        $(".subnav01").toggle ("slide", {direction: "right"}, "slow");
        $(this).toggleClass("active");
    });
    $(".menuproducts").on("click", function(){
        reset();
        $(".subnav02").toggle ("slide", {direction: "right"}, "slow");
        $(this).toggleClass("active");
    });
    function reset() {
        $("ul.nav li").removeClass("active");
        $("ul.nav li ul").hide();        
    }
});

你也可以稍微重构你的代码，这样它就不会那么重复了。添加更多根导航元素意味着每次都复制代码：）
