我有一个菜单，当你点击汉堡图标时，我想下拉菜单。点击按钮后显示列表项，但当按钮未被点击时仍然可以看到列表项。我无法弄清楚如何隐藏菜单。切换菜单列表项目显示
我这里的代码：Codepen
function myFunction() {
\t var x = document.getElementById("myTopnav");
\t if (x.className === "topnav") {
\t x.className += " responsive";
\t } else {
\t x.className = "topnav";
\t }
\t }
$(document).ready(function() {
$('#nav-icon3').on('click', function() {
$(this).toggleClass('open');
});
});* {
\t box-sizing: border-box;
