This is a PHP Shortcode allowing us to create an accordion directly in the WordPress WYSIWYG editor using the structure: [accordion_block]...[/accordion_block].Within the shortcode, all <h3> tags are automatically mapped as accordion titles, with any content between two <h3> tags serving as that title's associated content.The PHP code processes this input and generates the necessary HTML markup.jQuery handles interactivity, implementing an exclusive accordion pattern where only one item can be open at a time.

The component's appearance is controlled by CSS, which must be adjusted to your specific design requirements as styling is subjective. Dummy Use Case (Creating a FAQ Section)You can paste the following content directly into your WordPress page editor (in the Text or Code view) and the shortcode will transform it into a functional, styled accordion:
