Lightweight Accordion plugin for WordPress allows you to add collapse elements to posts using a Gutenberg block or a shortcode (via classic editor). By using the details HTML tag and a few lines of CSS this allows for a javascript-free accordion for minimum page load.

Extremely Lightweight (<1kb): Without using Javascript the plugin uses the native details HTML tag and a few lines of code for almost no impact on front-end.
Customizable: Options include customizing the HTML tag used for the accordion title, open by default, borders, colors, and accordion grouping (auto-close others when one opens).
<h4>Shortcode Usage examples</h4>

Here are a few examples of using the accordion plugin with shortcodes.
<pre><code>[lightweight-accordion title="My Accordion"]My Content[/lightweight-accordion]
</code></pre>
Additionally you can display the accordion open on load with the accordion_open option.
<pre><code>[lightweight-accordion title="My Accordion" accordion_open=true]My Content[/lightweight-accordion]
</code></pre>
You can also change the html tag wrapping the title of the accordion using the title_tag option.
<pre><code>[lightweight-accordion title="My Accordion" title_tag="h3"]My Content[/lightweight-accordion]
</code></pre>
If you want to include FAQ schema you can add the schema option and set it to faq.
<pre><code>[lightweight-accordion title="What is your return policy?" schema="faq"]You have 1 week to return your items[/lightweight-accordion]
</code></pre>
If you’d like put a border around the content of the accordion you can use the “bordered” attribute.
<pre><code>[lightweight-accordion title="Bordered Content" bordered=true]My Content[/lightweight-accordion]
</code></pre>
If you want accordions to auto-close when another opens (exclusive accordion), use the “group” attribute with the same value on each accordion.
<pre><code>[lightweight-accordion title="Question 1" group="faq"]Answer 1[/lightweight-accordion]
[lightweight-accordion title="Question 2" group="faq"]Answer 2[/lightweight-accordion]
[lightweight-accordion title="Question 3" group="faq"]Answer 3[/lightweight-accordion]
</code></pre>
<h4>Shortcode Options</h4>
Here is the full listing of shortcode options. Additionally all of these options are accessible when using the Gutenberg block.
<ul>
<li>title (Required Default: null) The title of your accordion will be displayed at the top for users to click. A good example would be to include a user’s question so they could click it for more details.</li>
<li>content (Required Default: null) Content that will go into your accordion element.</li>
<li>title_tag (Default: “span”) This sets the html tag that wraps the title in the accordion summary. Useful if you want to make it a heading tag for SEO purposes.</li>
<li>accordion_open (Default: false) Set this to true if you want your accordion to be open by default.</li>
<li>bordered (Default: false) Set this to true if you want a border around the accordion content.</li>
<li>title_text_color (Default: false) Set this to a hex value or CSS color to change the color of the accordion title text.</li>
<li>title_background_color (Default: false) Set this to a hex value or CSS color to change the color of the accordion title text.</li>
<li>schema (Default: false) Set this to faq if you’d like FAQ schema to be included.</li>
<li>class (Default: false) Used to add a custom class to the parent container of the accordion.</li>
<li>anchor (Default: null) Adds the value as an ID to the accordion div as an anchor.</li>
<li>autop (Default: true) By default the shortcode will wrap text in a ‘p’ tag. Set this to false if you’d like this disabled for the specific accordion.</li>
<li>group (Default: false) Set this to a group name to make accordions with the same group auto-close when another opens. Uses the native HTML details name attribute for zero JavaScript overhead.</li>
</ul>
<h4>Additional Details</h4>
If you’d like to remove the “lightweight-accordion.css” from being enqueued on your site use the filter below. It’s recommend you style the accordion yourself if you use this filter.
<pre><code>add_filter('lightweight_accordion_include_frontend_stylesheet', '__return_false' );
</code></pre>
If you’d like to remove the “lightweight-accordion/editor-styles.css” from being enqueued in the admin area of your site you can use the filter below.
<pre><code>add_filter('lightweight_accordion_include_admin_stylesheet', '__return_false' );
</code></pre>
If you’d like to remove processing of shortcodes in accordion content you can use this filter.
<pre><code>add_filter('lightweight_accordion_process_shortcodes', '__return_false' );
</code></pre>
If you’d like to use inline Microdata for FAQ schema you can use this filter. (Not recommended)
<pre><code>add_filter('lightweight_accordion_output_microdata', '__return_true' );
</code></pre>
If you’d like to force “lightweight-accordion.css” to load on all of your site you can use this filter. By default the plugin will detect if the block or shortcode is used and enqueue the CSS.
<pre><code>add_filter('lightweight_accordion_always_include_frontend_stylesheet', '__return_true' );
</code></pre>

Lightweight Accordion

Thanks for this plugin mate. It's a timesaver.

Love!

You can tell when a plug-in author has really put some thought into it. The plugin does what it is supposed to do and, unlike the competition, does not need Javascript. Anyone who values high PageSpeed should opt for this plugin. Great work!

I was looking for a simple and lightweight plugin for adding an Accordion FAQ in the Classic Editor. This one does the job, I like it. Did not use the block yet..

First – differently than any other similar plugin, this plugin is based on MIT license, which is a holly-grail for premium theme authors on i.e. ThemeForest or similar marketplaces. 
Differently to standard GPLv2 license you are not required to open-source your theme and you CAN include this plugin into your premium websites bundle packs. 
I do say here bundle packs, because you should never have an F.A.Q. to be a part of your theme, because that would be a bad idea – you need to leave your customers a flexibility for the future scale: 
What if your customers will decide later go with some kind of fancy knowledge base system like in Change.org <code>/help/</code> part or Envato.com <code>Support</code> part – if your customer will grow that big, he won’t need to have F.A.Q. plugin anymore on their website, he will want to replace it with that fancy knowledge base system. 
So my advise is to include this plugin in your bundle pack’s <code>/Optional Plugins/</code> folder, so that you can tell about in the installation instructions, but make it fully independent from your theme.
Second – this plugin is fully MVC + Templates based. This means that it’s code is not related at all to it’s UI, and that allows you easily to override it’s UI templates and Assets (CSS, JS, Images) by your theme very easily (and there is detailed step-by-step instructions given how to do that). 
This means that you making a theme to be what the theme has to be – a UI part of your website, nothing more.
Third – it is much more secure than any other plugin’s on the market. It is based on top-end S.O.L.I.D. coding principle with input data validation with data-patterns, output escaping.
Fourth – this plugin is scalable – it’s source code is fully object-oriented, clean & logical, based on MVC architectural pattern with templates engine, compliant with strict PSR-2 coding standard and PSR-4 autoloaders, and easy to understand how to add new features on your own.
Fifth – this plugin works well with big databases & high-traffic websites – it is created on optimal BCNF database structure and was tested on live website with 1M customers database and 500,000 active daily views.
Sixth – it does support official WordPress multisite as network-enabled plugin, as well as it does have support WPML string translation. 
At this point, if you need more than one language, I’d strongly advise to go with official WordPress multisite setup, because it is free, it is official (so you will never need to worry about the future support), and, most important – WordPress multisite is much more suitable for websites that needs to scale. You don’t want to have that additional translation bottle-neck code layer to be processed via database.
Seventh – it has nice user experience – it’s has a default design, it does allow you to have more than one F.A.Q. item open at the same time – so it don’t have that annoying <code>accordion</code> feature.
But the most important is that this plugin is and always be ads-free. I personally really hate these freemium, ads-full or tracking plugins which makes majority of the plugins on w.org plugins directory (and, actually, many of premium marketplaces). So this is the key features we always maintain: 
1. Never track your data (nor even by putting some kind of GDPR-compliance agreement checkbox, like <code>Error Log Monitor</code> plugin), 
2. Never make it pseudo-ads-full (even such a big plugins like <code>WooCommerce</code> or <code>Contact Form 7</code> has nearly 80% of their home screen or 20% of their main buttons about <code>how to install \ buy other plugins</code> 
– this is a really ugly behavior of pushing-more and going to Facebook-like business, where you get like drug-addicted to company products).
The goal of this plugin is to full-fill the needs of website-starter, that needs a great tool which can last him for many years until it will grow that big so he would grow-out current plugins and would need some kind of different plugins.
And, I believe, that many other developers had the same issue when tried to create their first premium theme or set-up a website for their client. Starting with the issues with license type to the moment when F.A.Q. is <code>hardcoded</code> into theme code.
So I wanted to help all these developers to save their time, and I’m releasing this plugin for you to simplify your work. And I’m releasing it under MIT license, which allows you to use this plugin your website bundle without any restrictions for both – free and commercial use.
Plus – I’m giving a promise to you, that this plugin is and will always be 100% free, without any ads, ‘Subscribe’, ‘Follow us’, ‘Check our page’, ‘Get Pro Version’ or similar links.
Finally – the code is poetry – the better is the web, the happier is the world.

Expandable FAQ

The best FAQ plugin on the market that has absolutely NO ADS. I love to use it on my ThemeForest Envato themes :).
