Documentation

Select the Carousel Slider block from the Design category. Click the + button located at the end of the carousel to add slides. Add any block within the slides. Use the horizontal scrollbar to preview the slides in the editor.

You can reorder the slides by using the left and right arrow buttons in the toolbar.

To remove a slide, select the slide and click the three dots right above it. Click the option to remove that slide.

Click the Carousel Block (the block nesting all the slides) to show the carousel settings.

Carousel Slider Version 2

Carousel Slider v2 now uses Swiper.js instead of Slick. It’s more modern, better supported, and works smoother across devices.

Upgrading from Legacy Carousel

• Existing legacy (v1) Carousel Slider blocks will still work. You can re-enable them in the admin settings under Settings → Carousel Slider.
• To upgrade, click on a legacy Carousel Slider block in the editor. In the block’s toolbar (the floating bar that appears above the block), click the block icon (first button on the left). From the dropdown, choose “Transform to Carousel Slider v2”. Your existing carousel settings will be preserved, but note that the design and HTML markup will change.
• Legacy styles will not apply to v2. You may need to adjust custom CSS.

Optional: Re-enable Legacy Blocks

You can show/hide legacy blocks from the block inserter and disable v2 upgrade notices via Settings → Carousel Slider in the admin menu.

Note: Legacy blocks will continue to function, but are no longer supported. It is highly recommended to upgrade to v2 for continued improvements and compatibility.
