<h3>Developer Notes</h3>
<h4>Registering Custom Block Variations</h4>
<p>You can register custom carousel variations using <code>wp.blocks.registerBlockVariation()</code> and pass Splide configuration options via the <code>splideOptions</code> attribute.</p>
<p><strong>Example: Carousel with Grid Fallback at Tablet</strong></p>
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
  name: 'carousel-to-tablet',
  title: 'Carousel / Grid Tablet',
  attributes: {
    template: 'default',
    splideOptions: {
      type: 'loop',
      perPage: 1,
      arrows: true,
      pagination: true
    },
    breakpoints: {
      tablet: {
        layout: {
          type: 'grid',
          columnCount: 3
        }
      }
    }
  },
  scope: ['block', 'inserter', 'transform']
});
</code></pre>
<p><strong>Example: Auto-Width Carousel</strong></p>
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
  name: 'auto-width-carousel',
  title: 'Auto Width Carousel',
  attributes: {
    splideOptions: {
      type: 'loop',
      fixedWidth: '300px',
      focus: 'center',
      gap: '1rem'
    }
  }
});
</code></pre>
<h4>Adding Custom Templates</h4>
<p>Use the <code>groundworx.carousel.templates</code> filter to add custom templates:</p>
<pre><code>wp.hooks.addFilter(
  'groundworx.carousel.templates',
  'my-theme/add-custom-template',
  (templates) => [
    ...templates,
    {
      label: 'My Custom Template',
      value: 'my-custom'
    }
  ]
);
</code></pre>
<p>Then add your template styles in your theme:</p>
<pre><code>.template-my-custom .splide__slide {
  /* Your custom styles */
}
</code></pre>
<h4>Supported Breakpoints</h4>
<p>The carousel supports 7 configurable responsive breakpoints plus a mobile/default base, following a mobile-first approach:</p>
<ul>
<li><strong>Mobile/Default</strong>: 0-374px (base configuration)</li>
<li><strong>phone</strong>: 375px and up</li>
<li><strong>large-phone</strong>: 480px and up</li>
<li><strong>tablet</strong>: 680px and up</li>

<li><strong>desktop</strong>: 1280px and up</li>
<li><strong>large-desktop</strong>: 1440px and up</li>
</ul>
<p>Settings cascade from mobile to larger screens. Override at any breakpoint to change behavior.</p>
<p><strong>Grid Fallback Breakpoints:</strong><br />
For grid fallback functionality, you can use any of the 7 breakpoints: <code>phone</code>, <code>large-phone</code>, <code>tablet</code>, <code>large-tablet</code>, <code>laptop</code>, <code>desktop</code>, or <code>large-desktop</code>.</p>
<h4>Splide.js Options</h4>

Thank you John West for bringing this fantastic plugin back to life :) I published many tutorials years ago and thought they would go to waste. But now I can keep them running and of course I have to also update some of them. 

When I have the time, I will help with the Spanish translation :)

Well done. 

Thank you

Completely free, open source plugin to easily add slideshows to your WordPress site.
