var panel = button.nextElementSibling;
panel.style.maxHeight = null;
}
var acc = document.getElementsByClassName("accordion");
for (var i = 0; i < acc.length; i++) {
acc[i].addEventListener("click", function() {
// Close all other accordions
for (var j = 0; j < acc.length; j++) {
var button = acc[j];
if (button === this) continue;
button.classList.remove("active");
var panel = button.nextElementSibling;

this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.maxHeight) {
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight + "px";
}
});
