WordPress Accordion Block: 3 Easy Methods to Get Started

Want to organize your WordPress content in a clean, user-friendly way? That’s where accordion blocks come in! Whether you’re creating an FAQ section, hiding lengthy content, or making your blog post more scannable, accordion blocks can help.

In this guide, I will discuss:

• What accordion blocks are

• Why and when to use them

• How to add accordion blocks (with and without plugins)

• The best WordPress accordion plugins available

And a lot more. If you want to know in-depth about the WordPress accordion block, this article is for you. So, without any further ado, let’s get started!

🔍 What Is a WordPress Accordion Block (And When to Use It)

A WordPress accordion block is a collapsible content element that allows users to expand and collapse sections of text. It helps you organize long-form content into neat, clickable sections — to improve readability and user experience.

Instead of showing all your content at once (which can overwhelm readers), accordion blocks reveal content only when a section is clicked.

🧠 When Should You Use an Accordion Block?

Here are some practical use cases for accordion blocks on your WordPress site:

FAQs – suitable for displaying questions and answers in an organized manner. Users can quickly find the answers they need without distraction.

Product Details or Specs – If you have an e-commerce site, you need to showcase technical details about your products. Accordions can be a great way to display that info.

Lesson Breakdowns – For education websites, specifically for course curriculum –  accordion blocks can better present specific topics to be discussed.

Terms, Conditions, or Policies – Legal pages often contain multiple sections. Using accordions helps make them easier to navigate.

In short, if you have lots of content that users might want to scan or read selectively, an accordion block is a smart and user-friendly choice.

What Benefits Does the Accordion Block Offer?

Accordion blocks aren’t just visually appealing — they bring practical benefits to both you and your visitors. Here are the essential advantages it brings:

They help you group related content under expandable headers. This lets you declutter webpages and ensures easier navigation for complex information.

So, you don’t have to overwhelm your readers with walls of text – instead, use accordions to present only the most important details.

Also, accordion blocks ensure a professional look on your website. This leads to a better user experience and improved dwell time.

In addition, you can easily apply this block to your website using a dedicated plugin like PostX – no need for complicated setup. You can tweak the icons, colors, and many other settings for the block to give your webpages a unique look.

In the next sections, you will learn different methods to show accordion blocks in your WordPress site.

✅ Method 1: Add Accordion Using the WordPress “Details” Block

If you want to add an accordion without using any plugin, you can utilize the built-in block of WordPress called “Details”. 

It is the easiest way to present a collapsible section on your website – without the help of custom code or a dedicated plugin. 

Here are the steps you need to follow:

• Open the WordPress block editor (edit or create a post/page).

• Click the “+” button to add a new block.

• Search for the “Details” block and add it

• Click on the block, and you should be able to give the accordion any text heading.

• Under this block, you can add other blocks such as text, heading, etc.

Customization Tips:

Change Text Colors or Background: Click the block, go to the right sidebar, and under “Styles”, you’ll find color and typography settings.

Typography: Adjust the font size to make the accordion stand out.

Background: A/b test different background colors and see which one suits your style.

Icons: WordPress doesn’t yet support icons by default in the <details> block, but you can use emojis (👉, ▼, ➕) in the summary to simulate a toggle feel.

Spacing: Use margin and padding options to make your accordion blend better with other content on the page.

This method is lightweight and works out of the box — ideal for FAQs and simple collapsible sections.

💻 Method 2: Add Accordion Using Custom HTML & CSS 

If you want a bit more customization than WordPress’s default “Details” block, but don’t want to install a plugin, you can create collapsible sections using simple HTML and CSS. 

This method gives you better control over the design, colors, spacing, and behavior.

Step-by-Step Guide:

1. Open the page/post you want to edit in the WordPress block editor.

2. Add a Custom HTML block where you want the accordion.

3. Paste this HTML snippet:

<details class="custom-accordion">  <summary>What is the best accordion plugin for WordPress?</summary>  <p>One of the best accordion plugins for WordPress is PostX. It offers a dedicated Accordion block with full styling and advanced customization options - no coding required. </p></details>

4. Now, to make it look clean and professional, you can add a bit of CSS to it. Visit your WordPress dashboard and go to Appearance → Customize → Additional CSS, and add this:

.custom-accordion {  margin-bottom: 15px;  border: 1px solid #ddd;  border-radius: 6px;  padding: 12px;  background-color: #f7f9fc;  transition: all 0.3s ease;}
.custom-accordion summary {  cursor: pointer;  font-weight: 600;  font-size: 1.1rem;  color: #1F66FF; /* blueish heading */}
.custom-accordion[open] {  background-color: #ffffff;  border-color: #1F66FF;  box-shadow: 0 0 5px rgba(31, 102, 255, 0.15);}
.custom-accordion p {  margin-top: 10px;  font-size: 0.95rem;  line-height: 1.5;  color: #333;}
