Customize the Carousel Output

When you need to change the markup a carousel emits – to wrap it in a container, add a heading, or post-process the HTML – use the nbc_shortcode_filter.

The filter

It passes the rendered HTML and the shortcode attributes, and expects you to return the (possibly modified) HTML.

add_filter( 'nbc_shortcode_filter', function ( $output, $atts ) {
	return '<div class="my-carousel-wrap">' . $output . '</div>';
}, 10, 2 );

Tips

• Return a string. Returning an empty string hides the carousel.
• Use $atts['id'] to target a single carousel only.
• Escape any dynamic values you add to the output.
