【问题描述】：
所以我已经尝试了所有方法，但我似乎仍然无法将下拉内容与 dropbtn 对齐。我只是希望内容始终位于更多菜单下方。

CSS：
#container{
width:1000px;
padding:100px 0;
margin:0px auto;
}
.menu{
padding:0;
}
.nav{
overflow: hidden;
text-align:center;
margin: 0 auto;
}
.nav a, .dropbtn {
display: inline-block;
color: black;
font-family: sans-serif;
text-decoration:none;
font-size: 17px;
padding: 40px;
}
.nav a:hover{
color: #DBB569;
}
.nav li{
display: inline-block;
}
li a.active {
color: #DBB569;
}
.nav .icon {
display: none;
}
.dropdown .dropbtn {
border: none;
outline: none;
background-color: white;
}
.dropdown-content {
display: none;
position: absolute;
max-width:200px;
-webkit-box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
background-color:white;
z-index: 1;
margin-top: -1.5em;
padding: 0;
list-style: none;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
}
.dropdown:hover .dropdown-content {
display: block;
}
@media screen and (max-width: 959px){
#container,p{
width: 100%;
}
.nav a, .dropbtn{
padding: 30px;
}
}
@media screen and (max-width: 640px){
.nav a, .dropbtn {
padding:20px;
}
}
@media screen and (max-width: 320px){
#container{
width: 320px;
}
}
JS（负责在More中一路隐藏物品）：
var all_widths = [110.64,144.64,199.14,135.19,162.59,115.63];
$(document).ready(function(){
var item_count = ($( "#menu li" ).length);
var menu_width = ($("#menu").width());
var items_width = 0;
for(var i = 0; i<item_count;i++){
items_width += all_widths[i];
}
while(menu_width < items_width + 20){
items_width-= $('#menu li').not('#more').last().width();
$('#menu li').not('#more').last().appendTo($('.dropdown-content'));
$('#more').appendTo($('#menu'));
$('#more').show();
}
$(window).resize(function(){
var item_count = ($( "#menu li" ).length);
var menu_width = ($("#menu").width());
var items_width = 0;
var bool = new Boolean(false);
for(var i = 0; i < item_count; i++){
items_width += all_widths[i];
}
while(menu_width < items_width + 20){
items_width -= $('#menu li').not('#more').last().width();
$('#menu li').not('#more').last().appendTo($('.dropdown-content'));
$('#more').appendTo($('#menu'));
$('#more').show();
bool = true;
}
while ((menu_width >= items_width + all_widths[item_count-1]) && bool == false){
items_width += all_widths[item_count-1];
$('.dropdown-content li').not('#stay').last().appendTo($('#menu'));
$('#more').appendTo($('#menu'))
}
});
$('#more').click(function(){
$('.dropdown-content').slideToggle();
});
});

你能帮我弄清楚如何让它工作吗？我已经尝试了所有我能记住的东西，我只需要了解如何真正让它工作静态但也能响应。非常感谢！
