Accordion Blocks


Accordion Blocks is a simple plugin that adds a Gutenberg block for adding accordion drop-downs to your pages.

The accordions should blend seamlessly with your theme. However, you may want to add custom styles to your theme.


  • Adds a Gutenberg block for adding accordions to your site.
  • Supports multiple accordions with individual settings for each accordion item.
  • Fully responsive.
  • Support for item IDs and direct links.
  • Accessible (for users requiring tabbed keyboard navigation control).

Optional Features

  • Open individual accordion items by default.
  • Disable auto closing of accordion items.
  • Manually close items by clicking the title again.
  • Scroll page to title when it’s clicked open (including setting a scroll offset position).
  • Set the HTML heading tag for the title element (h1–h4, button).
  • Set defaults to be applied to all new accordion items or reset a specific accordion item to the defaults.
  • Supports adding custom block styles using wp.blocks.registerBlockStyle.


The plugin will ultimately output following HTML (simplified for this example):

<div class="wp-block-pb-accordion-item c-accordion__item js-accordion-item" data-initially-open="false" data-click-to-close="true" data-auto-close="true" data-scroll="false" data-scroll-offset="0">
    <h2 id="at-76840" class="c-accordion__title js-accordion-controller" tabindex="0" role="button" aria-controls="ac-76840" aria-expanded="false">
        Title with H2 tag
    <div id="ac-76840" class="c-accordion__content" style="display:none" aria-hidden="true">

Custom CSS

You can use the following CSS classes to customize the look of the accordion.

.c-accordion__item {} /* The accordion item container */ {} /* is-open is added to open accordion items */ {} /* is-read is added to accordion items that have been opened at least once */
.c-accordion__title {} /* An accordion item title */
.c-accordion__title--button {} /* An accordion item title that is using a `<button>` tag */
.c-accordion__title:hover {} /* To modify the style when hovering over an accordion item title */
.c-accordion__title:focus {} /* To modify the style when an accordion item title currently has broswer focus */
.c-accordion__content {} /* An accordion item content container */

Accordion Blocks


  1. Upload the ‘accordion-blocks’ folder to the ‘/wp-content/plugins/’ directory.
  2. Activate the plugin through the Plugins menu in WordPress.
  3. Add the accordions to your content.


Can I change all my existing accordion items to the defaults?

No. It is not possible to change all your accordion item’s settings (within the same page or across multiple pages) to the defaults.

Although I would like to offer this feature, based on my research it would require a significant amount of development time that I am unable to devote to a free plugin. If you are a developer and would be interested in helping implement a feature like that, please let me know.

Why isn’t the JavaScript file loading on my site?

This is most likely caused by a poorly coded theme. This plugin makes use of the wp_footer() function to load the JavaScript file and it’s dependancy (jQuery). Check your theme to ensure that the wp_footer() function is being called right before the closing </body> tag in your theme’s footer.php file.


For bug reports or feature requests or if you’d like to contribute to the plugin you can check everything out on Github.

Thanks Phil, this is exactly what I was looking for but didn't even know it! An elegant solution to setting up accordion blocks without any cruft!

This plugin has everything you need: It's very lightweight; it's clean and beautiful; it's simple to use, yet it has enough options so it fits every need; it's translatable; and supports Gutenberg blocks. It only needs support for nested items, but not everybody needs this.

Having used the original Accordion Shortcodes for many years, when I saw the name behind this great simple block I just new it would be a keeper. Simplicity always wins. 🙂

Changelog (registro delle modifiche)


  • Fixed: Use sample content (instead of real content) to preview custom blocks styles in the editor.
  • Fixed: Bumped required version to WordPress 5.4.


  • Fixed: Resolved issue with PHP notice for not setting permission_callback in REST API.


  • Added: Support for WordPress 5.5

  • Fixed: An issue where, on some sites, accordion content would not smoothly animate open, instead just appearing instantly after a short delay
