<h4>Part of Groundworx Core</h4>
This carousel block is part of the Groundworx Block Suite—a modular collection of high-performance, design-focused blocks built for modern WordPress development. Uses Groundworx Foundation components for consistent, professional UI controls.
<h4>Need More? Check Out Groundworx Showcase</h4>
Groundworx Carousel is a self-contained carousel block — you add slides manually, and navigation (arrows, pagination, etc.) is built into the block itself. It’s a great fit for static content like testimonials, feature highlights, or image galleries where you control every slide.
<a href="https://groundworx.dev/products/groundworx-showcase/" rel="nofollow ugc">Groundworx Showcase</a> takes a fundamentally different approach: a modular block system where every piece — the carousel, the slides, and each navigation control — is its own independent block. 12 blocks, 4 flow types, and full query support.
Query & Content:
<ul>
<li>Query-driven carousels — Pull slides automatically from posts, pages, custom post types, or WooCommerce products. Filter by taxonomies, date, authors, keyword, and post formats. Set max items and sort order. Or switch to Curated mode to hand-pick specific posts.</li>
<li>Block pattern support — Design your slide layout with blocks (title, excerpt, image, buttons — whatever you want), and every queried post fills that pattern. Works just like WordPress’s Query Loop block — pick a pattern, change it later, every slide updates.</li>
<li>4 Flow types — Dynamic Flow (query carousel), Static Flow (manual carousel), Dynamic Content (query grid/flex), and Flow Template (reusable slide pattern). Dynamic Content outputs the same query to grid or flex layouts instead of a carousel.</li>
</ul>
Modular Controls:
<ul>
<li>Independent navigation blocks — Arrows, pagination, progress bar, and counter are separate blocks inside the carousel. Wrap them in groups, columns, or any container block to build your own layout — they’re not locked to fixed positions.</li>
<li>More control over every component — Each piece is its own block with its own settings, spacing, and layout options.</li>
</ul>
Carousel Options:
<ul>
<li>More modes — Fade transitions, vertical slides, auto-scroll (continuous scrolling), and RTL text direction — in addition to slide and loop.</li>
<li>Fine-grained timing — Customizable slide animation duration, autoplay with configurable interval, auto-scroll with configurable speed, and pause-on-hover for both autoplay and auto-scroll.</li>
<li>Video support — Videos automatically pause when their slide is not active.</li>
<li>Per-breakpoint layout switching — Switch between carousel, grid, and flex at every breakpoint independently. For example: carousel on mobile, grid on tablet, carousel again on desktop. Carousel only supports a one-way break to grid — once destroyed, it stays grid at all larger breakpoints.</li>
</ul>
Carousel vs. Showcase at a glance:
<ul>
<li>Carousel: One block, manual slides, built-in navigation, slide/loop modes, one-way grid fallback — simple and self-contained</li>
<li>Showcase: 12 modular blocks, query-driven or curated, slide/loop/fade/auto-scroll modes, vertical slides, RTL, per-breakpoint carousel/grid/flex switching — flexible and composable</li>
</ul>
Showcase is ideal when you need:
<ul>
<li>Carousels that populate automatically from your content</li>
<li>Block patterns applied to query-driven slides — like the Query Loop block, but for carousels</li>
<li>Full control over navigation layout — wrap controls in any block container</li>
<li>The same query powering both carousel and grid views</li>
</ul>

<h3>Developer Notes</h3>
<h4>Registering Custom Block Variations</h4>
You can register custom carousel variations using <code>wp.blocks.registerBlockVariation()</code> and pass carousel configuration options via the <code>carouselOptions</code> attribute.
Example: Carousel with Grid Fallback at Tablet
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
 name: 'carousel-to-tablet',
 title: 'Carousel / Grid Tablet',
 attributes: {
 template: 'default',
 carouselOptions: {
 type: 'loop',
 perPage: 1,
 arrows: true,
 pagination: true,
 containScroll: 'trimSnaps',
 breakpoints: {
 tablet: {
 destroy: true
 }
 }
 },
 breakpoints: {
 tablet: {
 layout: {
 type: 'grid',
 columnCount: 3
 }
 }
 }
 },
 scope: ['block', 'inserter', 'transform']
});
</code></pre>
Example: Auto-Width Carousel
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
 name: 'auto-width-carousel',
 title: 'Auto Width Carousel',
 attributes: {
 carouselOptions: {
 type: 'loop',
 fixedWidth: '300px',
 align: 'center',
 gap: '1rem'
 }
 }
});
</code></pre>
<h4>Adding Custom Templates</h4>
Use the <code>groundworx.carousel.templates</code> filter to add custom templates:
<pre><code>wp.hooks.addFilter(
 'groundworx.carousel.templates',
 'my-theme/add-custom-template',
 (templates) => [
 ...templates,
 {
 label: 'My Custom Template',
 value: 'my-custom'
 }
 ]
);
</code></pre>
Then add your template styles in your theme:
<pre><code>.wp-block-groundworx-carousel.template-my-custom .gwx-carousel__slide {
 /* Your custom styles */
}
</code></pre>
<h4>Supported Breakpoints</h4>
The carousel supports 5 configurable responsive breakpoints plus a mobile/default base, following a mobile-first approach:
<ul>
<li>Mobile/Default: 0-479px (base configuration)</li>
<li>large-phone: 480px and up</li>
<li>tablet: 680px and up</li>
<li>laptop: 1080px and up</li>
<li>desktop: 1280px and up</li>
<li>large-desktop: 1440px and up</li>
</ul>
Settings cascade from mobile to larger screens. Override at any breakpoint to change behavior.
Grid Fallback Breakpoints: 
For grid fallback functionality, you can use any of the 5 breakpoints: <code>large-phone</code>, <code>tablet</code>, <code>laptop</code>, <code>desktop</code>, or <code>large-desktop</code>.
<h4>Carousel Options</h4>
Carousel options are configured via the <code>carouselOptions</code> attribute. Common options:
<ul>
<li><code>type</code>: ‘slide’ or ‘loop’</li>
<li><code>perPage</code>: Number of slides per page</li>
<li><code>slidesToScroll</code>: Number of slides to scroll per action (default: 1)</li>
<li><code>fixedWidth</code>: Fixed width for each slide (e.g., ‘300px’)</li>
<li><code>gap</code>: Space between slides</li>
<li><code>align</code>: Slide alignment — ‘start’, ‘center’, or ‘end’</li>
<li><code>containScroll</code>: Trim empty scroll snaps — ‘trimSnaps’ or false</li>
<li><code>autoplay</code>: Enable/disable autoplay</li>
<li><code>arrows</code>: Show/hide arrows</li>
<li><code>pagination</code>: Show/hide pagination</li>
<li><code>progressBar</code>: Show/hide progress bar</li>
<li><code>counter</code>: Show/hide slide counter</li>
<li><code>destroy</code>: Disable carousel and display as grid</li>
</ul>
Breakpoint-specific overrides are supported via the <code>breakpoints</code> attribute. Legacy <code>splideOptions</code> are automatically converted on render.
<h4>Color System</h4>
All UI element colors use the standard WordPress color pattern:
<ul>
<li>Preset colors apply WordPress utility classes (<code>has-text-color</code>, <code>has-{slug}-color</code>, <code>has-background</code>, <code>has-border-color</code>)</li>
<li>Custom colors apply inline styles</li>
</ul>
Pagination dot colors toggle dynamically between active and inactive states using the WordPress Interactivity API (<code>data-wp-class</code> for presets, <code>data-wp-style</code> for custom colors).
Elements with color support:
<ul>
<li>Arrows: text, background, border</li>
<li>Pagination (active): text, background (number style), border (number style)</li>
<li>Pagination (inactive): text, background (number style), border (number style)</li>
<li>Progress bar: track background, bar foreground</li>
<li>Counter: text</li>
</ul>
<h4>Template Classes</h4>
Each template adds a class to the carousel wrapper:
<ul>
<li><code>.template-default</code></li>
<li><code>.template-default-alt</code></li>
<li><code>.template-simple</code></li>
<li><code>.template-simple-left</code></li>
<li><code>.template-simple-right</code></li>
<li><code>.template-overlay</code></li>
<li><code>.template-overlay-alt</code></li>
<li><code>.template-partial-overlay</code></li>
<li><code>.template-partial-overlay-alt</code></li>
</ul>
Use these for template-specific styling.
