Add the following JavaScript function:
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");
});
