Any Block Carousel Slider is a Gutenberg carousel slider block plugin that instantly converts supported native WordPress blocks (Query Loop/Post Template, Group, Gallery) into a responsive carousel slider. Simply enable the “Carousel” toggle in the Gutenberg editor: your content stays 100% native, your DOM stays lightweight, and your Lighthouse performance scores remain intact. This includes WooCommerce product listings rendered via the Query Loop/Post Template block, so you can showcase products without relying on the legacy Products block.

Unlike many all-in-one carousel slider blocks that require you to add a dedicated “Carousel” block and rebuild every slide, Any Block Carousel Slider hooks straight into the Gutenberg blocks you already use. The result: a Query Loop/Post Template, Group, or Gallery block can become a carousel slider in one click, without content duplication or extra maintenance.
<h4>Why Any Block Carousel Slider instead of a dedicated carousel slider block?</h4>
<ul>
<li>WordPress loops without friction – Transform Query Loop and Post Template Gutenberg blocks into a “loop slider” without creating a block per slide.</li>
<li>Familiar editorial experience – Content editors keep the Gutenberg interface they know (patterns, global styles, alignments, inner blocks).</li>
<li>Native scroll & performance – Native CSS scroll-snap layout, GPU-friendly, no heavy Swiper/Slick bundle to load. Only a lightweight script handles navigation, loops, and autoplay.</li>
<li>Full compatibility – Works with classic themes and block themes while respecting the structure of your Query Loop/Post Template, Group, and Gallery blocks.</li>
<li>Accessibility + SEO – Keyboard navigation, respects <code>prefers-reduced-motion</code> preferences, clean DOM for crawling.</li>
</ul>
<h4>What you can do in 30 seconds</h4>
<ul>
<li>Blog / Magazine: Display your latest posts in a Query Loop carousel with native filters and badges.</li>
<li>Portfolios & testimonials: Keep your Group blocks and make them scrollable without rebuilding every slide.</li>
<li>Advanced galleries: Turn the Gallery block into a responsive slider while keeping all native settings.</li>
<li>Landing sections: Chain complex sections (image, title, buttons, forms) inside the same Group block and scroll them horizontally.</li>
<li>WooCommerce highlights: Use a Query Loop configured for products (featured, on sale, custom taxonomy) and convert it into a CSS-only product carousel.</li>
</ul>
<h4>Quick comparison</h4>
<ul>
<li>Activation: Any Block Carousel Slider – toggle an existing Gutenberg block. Classic carousel slider blocks – add a dedicated slider block and rebuild every slide.</li>
<li>WordPress loop: Any Block Carousel Slider – works with Query Loop and Post Template blocks without duplication. Competitor carousels – require one block per slide or custom code.</li>
<li>Frontend JavaScript: Any Block Carousel Slider – extremely lightweight script, CSS-powered carousel slider. Competitor carousels – load Swiper/Slick and additional scripts.</li>
<li>Performance: Any Block Carousel Slider – lightweight DOM, no external assets. Competitor carousels – multiply files, reflow, and downloads.</li>
<li>Content maintenance: Any Block Carousel Slider – single Gutenberg block to update. Competitor carousels – duplicate content in dedicated slides.</li>
<li>Security & upkeep: Any Block Carousel Slider – no third-party libraries to monitor. Competitor carousels – depend on external JS libraries like Swiper/Slick.</li>
</ul>
<h4>Key features</h4>
<ul>
<li>CSS-powered scroll – Smooth carousel slider with <code>scroll-snap</code> and lightweight JavaScript navigation controls. No heavy libraries.</li>
<li>Loop functionality – Enable infinite scrolling with seamless reset to start/end when reaching boundaries.</li>
<li>Autoplay support – Automatic slide progression with configurable delay and pause on hover/interaction.</li>
<li>Smart responsive – Automatically handles visible columns, spacing, and control sizes according to WordPress breakpoints (1280, 1024, 782, 600, 480, 375).</li>
<li>Two width modes – Manual mode (fixed column count) and Auto mode (fixed width like 320px) with automatic detection.</li>
<li>Gutenberg block spacing detection – Respects <code>gap</code> and <code>padding</code> values defined in the block editor, including presets.</li>
<li>Theme colors – Buttons automatically inherit your theme’s colors and radii (via CSS variables).</li>
<li>Intact semantics – Your Gutenberg block’s tags and classes remain unchanged: perfect for SEO, schemas, and E2E testing.</li>
<li>WooCommerce friendly – Query Loop can target the <code>product</code> post type, so WooCommerce grids become CSS-only carousels without a dedicated Products block integration.</li>
</ul>
<h4>Native Gutenberg block workflow</h4>
<ol>
<li>Add or edit one of the supported blocks (Gallery, Group, or Query Loop/Post Template).</li>
<li>Enable the Carousel option in the Gutenberg sidebar panel (Layout or Block section depending on the block).</li>
<li>Adjust your usual settings (column count, minimum width, spacing, alignment).</li>
<li>Save: your block becomes a touch-friendly, accessible, and SEO-friendly carousel slider.</li>
</ol>
<h4>Advanced customization</h4>
<ul>
<li>Loop mode – Enable infinite scrolling: when reaching the end, the carousel seamlessly resets to the beginning (and vice versa). Navigation buttons remain active at all times.</li>
<li>Autoplay – Automatic slide progression with configurable delay (default: 3000ms). Autoplay pauses on hover and user interaction, and stops at the end when loop is disabled.</li>
<li>Manual mode (fixed columns) – Ideal for article carousel sliders: 1 to 6 columns depending on screen sizes.</li>
<li>Auto mode (fixed width) – Perfect for card-based sliders (posts, testimonials, product highlights) with pixel-perfect widths like 280px, 320px, or 360px.</li>
<li>Padding and gaps – Automatic management via CSS vars <code>--carousel-padding-*</code>, <code>--wp--style--block-gap</code>.</li>
<li>Themes & <code>theme.json</code> – Override variables to align controls with your design system.</li>
<li>Cross-browser compatible – Works seamlessly on Chrome, Firefox, Safari, and all modern browsers with real HTML navigation controls.</li>
</ul>
<h4>Technical architecture</h4>
<ul>
<li><code>render_block</code> hook to inject variables based on context (block type, columns, gaps).</li>
<li>Dedicated service for translating labels and help messages.</li>
<li>Separate editor/frontend styles for a transparent Gutenberg experience.</li>
<li>Code organized by PSR-4 services.</li>
</ul>
<h3>How to use the plugin</h3>
<ol>
<li>Install and activate Any Block Carousel Slider from the Plugins screen (Plugins → Add New → search → Install → Activate).</li>
<li>Open the block editor, insert one of the supported blocks (Query Loop/Post Template, Group, Gallery), and toggle the Carousel option in the sidebar.</li>
<li>Ensure the carousel-enabled block sits inside a parent Group (or similar container) so the wrapper can manage overflow, spacing, and arrow positioning properly.</li>
<li>Switch the block layout to Grid then adjust the column count to match your design.</li>
</ol>

Any Block Carousel Slider


As a Native Blocks Carousel user, I’m impressed by how simple it is to turn carousels into Gutenberg. It’s the only plugin I know that truly converts any Gutenberg block into a carousel without compromises, while keeping every native feature intact. The interface is intuitive, the animation and navigation options are comprehensive, and the result stays fully responsive. Performance is excellent, and it adapts smoothly to any theme. Special mention for the clear documentation and translation support, which make multilingual setups a breeze. Kudos for this plugin—it delivers exactly what WordPress developers need: a native, clean, lightweight carousel solution.


Turn Any Gutenberg Block into a Carousel Effortlessly


This plugin turns WordPress native Posts/Query Loops, Galleries and Group blocks into carousels very easily– with just a checkbox! No duplication of content. So far, I found this to be the only option for seamless carousels if you want to keep things native.



An option to enable auto-slide would be a great addition. Also, if we could customize/add to the supported blocks for carousel enablement, then it could be even better.


Great Plugin for Native Block/Post Carousels

Transform any WordPress block into a responsive carousel using native CSS scroll-snap. Lightweight JS handles navigation, loops, and autoplay.

Thong Truong

Upon activating this plugin, you will not see any new menu page inside WP admin dashboard. Instead, this plugin adds a dynamic block straight to the block editor. You can then use the block settings sidebar to customize and edit everything related to the block.
This block picks the posts that have the same category/categories of the current post and display them in a carousel slider.
To insert and use the block, inside the post editor, underneath the main post content (or any position you wish), type ‘/related’, you should see the block called ‘Related Post Slider Block’. Choose and insert it to the post editor.
Here are the controls that you can customize and edit: 
✅ Display controls: 
 – Toggle on/off featured image for each slide. 
 – Toggle on/off category badge for each slide. 
 – Toggle on/off meta info(author, published date) for each slide. 
 – Toggle on/off excerpt for each slide. 
 – Display slide items in ASC/DESC order. 
 – Number of total posts to display. 
 – Number of posts per slide. 
✅ Responsive controls (desktop, tablet, mobile). 
✅ Dimension controls: 
 – Carousel padding/margin 
 – Slide item padding/margin 
✅ Style controls: 
 – Slide item border control 
 – Slide item border radius control 
 – Slide item box shadow control
