Lightweight Accordion

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. [youtube https://www.youtube.com/watch?v=Z8RcrtmzvUc] 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, orders, and colors. 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] 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.

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' );

To install this plugin:

1. Download the plugin
2. Upload the plugin to the wp-content/plugins directory,
3. Go to "plugins" in your WordPress admin, then click activate.
