Answer 1

Please refer this :
Use JavaScript and CSS for hide and show submenu on click or hover
document.addEventListener('click', function(e) {
e = e || window.event;
console.log(e);
var target = e.target || e.srcElement;
console.log(target);
if (target.parentElement.className.indexOf('has-submenu') > -1) {
e.target.classList.toggle('open');
}
}, false);

Answer 2

let arrow = document.querySelectorAll(".arrow");
for (var i = 0; i < arrow.length; i++) {
arrow[i].addEventListener("click", (e) => {
let arrowParent = e.target.parentElement.parentElement; //selecting main parent of arrow
arrowParent.classList.toggle("showMenu");
});
}
let sidebar = document.querySelector(".sidebar");
let sidebarBtn = document.querySelector(".bx-menu");
console.log(sidebarBtn);
sidebarBtn.addEventListener("click", () => {
sidebar.classList.toggle("close");
});
