How to Create a Vertical Tab Menu with CSS and JavaScript

Are you looking to add a sleek and interactive vertical tab menu to your website? In this article, we will guide you through the process of creating a vertical tab menu using CSS and JavaScript. We’ll also provide you with code snippets to help you implement it effectively. So, let’s get started!

1. Introduction

A vertical tab menu is a user-friendly navigation component that organizes content in a vertical manner, making it easy for users to access different sections of a website. By combining CSS and JavaScript, we can create an attractive and functional vertical tab menu. In this article, we will show you how to achieve this with step-by-step instructions and provide code snippets along the way.

2. Setting Up the HTML Structure

Let’s start by setting up the HTML structure for our vertical tab menu. We’ll use nested <div> elements to create the tabs and their associated content sections. Here’s an example of how the HTML structure should look:

<div class="tab-menu">
  <div class="tab">
    <button class="tablinks" onclick="openTab(event, 'tab1')">Tab 1</button>
  <div class="tab">
    <button class="tablinks" onclick="openTab(event, 'tab2')">Tab 2</button>
  <div class="tab">
    <button class="tablinks" onclick="openTab(event, 'tab3')">Tab 3</button>

<div class="tab-content">
  <div id="tab1" class="tabcontent">
    <h2>Tab 1 Content</h2>
    <p>This is the content for Tab 1.</p>
  <div id="tab2" class="tabcontent">
    <h2>Tab 2 Content</h2>
    <p>This is the content for Tab 2.</p>
  <div id="tab3" class="tabcontent">
    <h2>Tab 3 Content</h2>
    <p>This is the content for Tab 3.</p>

3. Styling the Tab Menu with CSS

Now that we have the HTML structure in place, let’s style the tab menu using CSS. We’ll use CSS to control the appearance and layout of the tabs and their content. Here’s an example CSS code snippet to get you started:

.tab-menu {
  display: flex;

.tab {
  flex: 1;
  margin-right: 10px;

.tablinks {
  display: block;
  width: 100%;
  padding: 10px;
  background-color: #f2f2f2;
  border: none;
  text-align: left;
  cursor: pointer;

.tablinks:hover {
  background-color: #ddd;

.tabcontent {
  display: none;

.tabcontent h2 {
  margin-top: 0;

4. Adding JavaScript Functionality

To make the tab menu interactive, we’ll add JavaScript functionality. JavaScript will allow us to toggle between tabs and display the corresponding content when a tab is clicked. Here’s an example JavaScript code snippet to achieve this:

function openTab(evt, tabName) {
  var i, tabcontent, tablinks;

  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";

  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {

  document.getElementById(tabName).style.display = "block";

// Set the default tab to be displayed
document.getElementById("tab1").style.display = "block";
