My go-to source for codes is usually https://www.w3schools.com. They also provide an accordion feature along with the code;
However, I've encountered an issue where when a link is used -> to The accordion doesn't open but remains closed. Does anyone know how to make the accordion open when linking to content inside it?
Thank you.
var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].onclick = function() {
this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.maxHeight){
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight + "px";
}
}
}
