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] If you’d like to swap the default triangle marker for a chevron or plus/minus icon (optionally on the right side of the title) use the “icon” and “icon_position” attributes. [lightweight-accordion title="My Accordion" icon="chevron" icon_position="right"]My Content[/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. icon (Default: false) Set this to “chevron”, “plus”, or “none” to replace the default triangle marker. The chevron rotates and the plus becomes a minus when the accordion opens. icon_position (Default: false) Set this to “right” to display the chevron or plus icon on the right side of the accordion title. Additional Details 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. add_filter('lightweight_accordion_include_frontend_stylesheet', '__return_false' ); 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. add_filter('lightweight_accordion_include_admin_stylesheet', '__return_false' ); If you’d like to remove processing of shortcodes in accordion content you can use this filter. add_filter('lightweight_accordion_process_shortcodes', '__return_false' ); If you’d like to use inline Microdata for FAQ schema you can use this filter. (Not recommended) add_filter('lightweight_accordion_output_microdata', '__return_true' ); 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. add_filter('lightweight_accordion_always_include_frontend_stylesheet', '__return_true' ); When a page contains an accordion a tiny inline script is added to the footer that automatically opens accordions targeted by a URL hash (for example a link to an accordion’s anchor). If you’d like to disable this you can use the filter below. add_filter('lightweight_accordion_anchor_script', '__return_false' );
