Lightweight Accordion for WordPress Plugin Directory

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).

Shortcode Usage examples

Here are a few examples of using the accordion plugin with shortcodes.

[lightweight-accordion title="My Accordion"]My Content[/lightweight-accordion]

Additionally you can display the accordion open on load with the accordion_open option.

[lightweight-accordion title="My Accordion" accordion_open=true]My Content[/lightweight-accordion]

You can also change the html tag wrapping the title of the accordion using the title_tag option.

[lightweight-accordion title="My Accordion" title_tag="h3"]My Content[/lightweight-accordion]

If you want to include FAQ schema you can add the schema option and set it to faq.

[lightweight-accordion title="What is your return policy?" schema="faq"]You have 1 week to return your items[/lightweight-accordion]

If you’d like put a border around the content of the accordion you can use the “bordered” attribute.

[lightweight-accordion title="Bordered Content" bordered=true]My Content[/lightweight-accordion]

If you want accordions to auto-close when another opens (exclusive accordion), use the “group” attribute with the same value on each accordion.

[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]

Shortcode Options Here is the full listing of shortcode options. Additionally all of these options are accessible when using the Gutenberg block.

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.

content (Required Default: null) Content that will go into your accordion element.

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.

accordion_open (Default: false) Set this to true if you want your accordion to be open by default.

bordered (Default: false) Set this to true if you want a border around the accordion content.

title_text_color (Default: false) Set this to a hex value or CSS color to change the color of the accordion title text.

title_background_color (Default: false) Set this to a hex value or CSS color to change the color of the accordion title text.

schema (Default: false) Set this to faq if you’d like FAQ schema to be included.

class (Default: false) Used to add a custom class to the parent container of the accordion.

anchor (Default: null) Adds the value as an ID to the accordion div as an anchor.

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.

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.
