Unlocking UI Secrets Use HTML’s <details> Element for Streamlined Accordions
Discover the power of HTML's element to create streamlined and user-friendly accordions. Learn how to simplify your UI design with this versatile HTML feature.
In the evolving world of web development, accessibility and simplicity are top priorities when designing user interfaces. Accordions—those useful collapsible sections commonly seen in FAQ pages, settings panels, and content-heavy sites—have long been a favorite tool to organize information efficiently. Traditionally, developers relied on JavaScript to build these collapsible sections, but modern HTML is offering simpler, more native ways to implement them. One such advancement is the
Accordions are UI patterns that allow users to expand and collapse sections of content. They are used to present content in a compact, accessible manner while avoiding information overload. Traditionally, accordions are built using custom JavaScript, but HTML is evolving to reduce reliance on external scripts, providing more native solutions.
The
This native HTML solution has long been appreciated for its simplicity. However, when building complex UI patterns, such as accordions, developers often need more functionality, such as exclusive behaviors—ensuring only one section is expanded at a time.
Exclusive accordions, also known as "single-open" accordions, are commonly used to improve user experience by automatically closing previously opened sections when a new one is clicked. Before recent updates, creating these exclusive behaviors required JavaScript.
For example, to build an exclusive accordion system, a developer might write custom JavaScript to track the state of each section, listen for clicks, and dynamically collapse or expand the appropriate content. This approach, while effective, added complexity and increased maintenance burdens.
Here’s a simplified example of JavaScript managing exclusive accordions:
While this solution works, it's clear that there’s a need for a simpler, more standardized method that doesn’t require writing or maintaining custom scripts.

Simplicity: The
Performance: By leveraging native HTML elements, pages load faster and are less resource-intensive. There’s no need for additional JavaScript libraries or code execution that could slow down performance.
Accessibility: Native HTML elements generally come with built-in accessibility features. The
Maintainability: By minimizing the use of custom JavaScript, the code becomes easier to maintain. Future developers or maintainers of a project can easily understand the functionality by examining the HTML structure, rather than having to decipher custom scripts.

What Are Accordions?
The
Element
element, it offers a simple way to present hidden content that can be revealed on demand. When a user clicks the summary, the content within the tag expands. If clicked again, the content collapses.
Basic Syntax:

const accordions = document.querySelectorAll('.accordion'); accordions.forEach(accordion => { accordion.addEventListener('click', function () { accordions.forEach(a => a !== this && a.classList.remove('active')); this.classList.toggle('active'); }); });HTML’s Solution The

name attribute allows grouping multiple elements, ensuring that only one of them can be open at a time—thus creating the exclusive behavior developers need.
Example:
<details name="accordion"> <summary>Section 1summary> <p>Content for section 1.p> details> <details name="accordion"> <summary>Section 2summary> <p>Content for section 2.p> details> <details name="accordion"> <summary>Section 3summary> <p>Content for section 3.p> details>name attribute, as soon as one
element in the same group will automatically close, delivering the desired exclusive accordion functionality—without needing JavaScript. This feature, available in modern browsers, simplifies the development process while enhancing performance and maintainability.

No longer do developers need to rely on custom JavaScript to achieve the desired behavior of collapsible sections. This HTML-based solution enhances accessibility, reduces complexity, and offers a performance-optimized alternative for building interactive user interfaces.
