jQuery Toggle Width Logic

I'm trying get expanding/ collapsing tabs on click so it's easy for the user to see which tab they're currently on.

I think what I want to do is to traverse through

<div class="sidebar">
's children and check each one for
During my traversal, if I find a child that has the class
, I want to stop there,
to whichever tab was originally clicked.

I'm not sure how to do this or if this is even the right way to approach at all.

$(".sidebar a").on('click', function() {

/*if( $(".sidebar").children().hasClass('clicked') ){


.sidebar {
position: fixed;
width: 14.5%;
top: 0;
bottom: 0;
text-decoration: none;
float: left;
display: inline-block;
padding-top: 2%;
padding-bottom: 2%;
z-index: 500;

.sidebar a {
color: whitesmoke;
background-color: #404040;
padding: 26% 20% 26% 15% ;
text-decoration: none;
box-shadow: 0px 0px 20px 0px rgba(0,0,0,0.2);
z-index: 800;
cursor: pointer;
width: 80%;

.item {
display: block;

.sidebar a.clicked {
width: 100%;

<script src=""></script>

<div class="sidebar">

<a href="#" class="item"> Item 1 </a>
<a href="#" class="item"> Item 2 </a>
<a href="#" class="item"> Item 3 </a>

You can just add the class to the clicked sidebar item and then remove it from all its siblings in one go, like so:

$(".sidebar").on("click", ".item", function() {
    return false;
