问题
I have a CSS collapse accordion with just pure CSS, it is working perfect.
I have just 1 issue: right now if the user click in any label: Label One, Label Two, Label Three, he can't close it clicking in Label again, each label can just close if the user clicks in the next one
I would like make it possible,
example: the user click in Label One to open, if him click again this label will close and the same will all for all labels.

I think the radio type will cause the problem, because it has only 2 "data-way".

if you want to use Jquery this code may help you
this is html
<div class="accordion">
<div class="group">
<a href="#" class="title">title 1</a>
<div class="content">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

<div class="group">
<a href="#" class="title">title 2</a>

this is css
.title{
text-decoration: none;
font-size: 17px;
display: block;
padding: 10px;
background: #ccc;
color: #fff;
border-bottom:1px solid #fff;
}
.group .content{
display: none;
padding: 10px;
background: #43ad43;
color: #fff;
}
.open .title{
background: green !important;
border-bottom:none;
}
.open .content{
display: block;
}
and this is jquery
$(document).ready(function () {
$('.title').on('click',function (e) {
e.preventDefault();
var parent=$(this).parent();
if (parent.hasClass('open')) {
parent.removeClass('open')
}
else{
$(".group").removeClass("open");
parent.addClass("open");
}
})
});
