Javascript DIV-won'；不要一直向下滚动

我又回来了，对我那个厚颜无耻的菜单提出了另一个问题。我终于完成了它，它在功能上完全正常，直到我在手机上检查它。当我展开所有菜单时，div将只滚动几个像素。我认为我的问题来自这样一个事实：一些元素有

溢出：隐藏
，并且主体和html高度设置为100%（在另一个文件中，即索引中。我提供的代码来自菜单文件，一个单独的文件）。这是我的分数：

这是我非常草率的JavaScript。如果你有任何简化它的建议，我会非常高兴，特别是在我看来，扩展菜单元素的代码非常草率，我认为我可以简化它，但我不知道如何做

if (navigator.appName == 'Microsoft Internet Explorer' ||  !!(navigator.userAgent.match(/Trident/) || navigator.userAgent.match(/rv:11/)) || (typeof $.browser !== "undefined" && $.browser.msie == 1))
{
    alert("Va rugam sa folositi alt browser cu site-ul nostru!Internet Explorer este un browser cu probleme de securitate, iar noi nu il suportam, asa ca veti fi redirectionati.Va multumim!");
    window.location.replace("http://www.google.com");
}
var button = document.querySelector('#buton-meniu');
var content = document.querySelector('#dropdown-meniu-content');

button.addEventListener('click', function(e) {
    e.stopPropagation();
    e.currentTarget.classList.toggle('change');
    content.classList.toggle('show');
}, true)

document.addEventListener('click', function() {
    if (content.classList.contains('show')) {
        content.classList.remove('show');
        button.classList.remove('change');
    }
})

content.addEventListener('click', function(e) {
    e.stopPropagation();
})
function expansiune_ferestre() {
    document.getElementById("dropdown-ferestre-content").classList.toggle("expand");
    document.getElementById("arrow-up-ferestre").classList.toggle("rotate");
}

    document.getElementById("dropdown-usi-content").classList.toggle("expand");
    document.getElementById("arrow-up-usi").classList.toggle("rotate");

    document.getElementById("arrow-up-sticla").classList.toggle("rotate");

    document.getElementById("dropdown-feronerie-content").classList.toggle("expand");
    document.getElementById("arrow-up-feronerie").classList.toggle("rotate");

这是代码的JSFIDLE:

感谢您的时间，我希望我的问题（如果您将查看javascript代码的请求计算在内）不会太傻
 这可能属于SE站点。JSFIDLE是错误的。我已经更新了它@bharat guptaI正在投票结束这个问题，因为它不属于主题，因为它更适合于代码审查。@删除“dropdown meniu content”类中有一个
min height
。卸下它，卷轴就可以正常工作了。
