function toggleMenu() {
console.log(‘hello’);
var menuBox = document.getElementById(‘dropdown-content-mobile’);
if(dropdown-content-mobile.style.display == “block”) { // if is menuBox displayed, hide it
dropdown-content-mobile.style.display = “none”;
}
else { // if is menuBox hidden, display it
dropdown-content-mobile.style.display = “block”;
}
}
I would check out that if statement. instead of using your declared variable menuBox, you are using an undefined variable dropdown-content-mobile which appears to be a css ID.
