Creating a JavaScript Accordion Without jQuery

Creating interactive elements like accordions on web pages can significantly enhance user experience. However, for beginners, understanding how to create them from scratch, especially without using frameworks like jQuery, can be a daunting task. In this guide, we will walk you through the process of creating an accordion using plain JavaScript.

The Problem: What Are We Trying to Achieve?

An accordion allows users to collapse and expand sections of content. This is particularly useful for FAQs or menu options, keeping the interface clean and user-friendly. The initial code snippet presented was a good start but did not include essential attributes like data-parent or data-toggle, which are necessary for proper functioning in a Bootstrap context.

Here's the aim: We want to create an accordion structure in JavaScript that mirrors this HTML structure:

The Solution: Step-by-Step Guide to Creating the Accordion

Let’s go through how to accomplish this using only JavaScript.

Step 1: Create the Parent Element

To get started, create the parent div that will house all the panels of the accordion:

This code snippet initializes the accordion and sets the necessary classes and ids to allow Bootstrap to style it correctly.

Step 2: Injecting the Inner HTML

Instead of manually creating each sub-element, you can use the innerHTML property to inject the panel structure directly into the accordion element. This simplifies our process and ensures the necessary attributes are included:

In this segment, we included the necessary data-parent, data-toggle, and href attributes that enable the accordion to function as intended.

Step 3: Append the Accordion to the Document

Finally, append the accordion structure to the appropriate location in your HTML document. In this example, we will append it to a div with the id navgroupsframe:
