Tabs Block – Responsive Gutenberg Tabs for Block Editor

Semantic markup that works with assistive technologies.

2. Responsive by Design No need for custom CSS or media queries. Tabs automatically adapt their layout across screen sizes:

On desktop: clean horizontal tab navigation.

On mobile: collapsible stacked layout or swipe-enabled scrolling.

3. Horizontal & Vertical Tabs Want sidebar-style navigation? Just toggle layout mode. You can switch between horizontal and vertical tabs at any time, perfect for documentation pages or feature lists.

4. Powered by the Interactivity API Unlike most tab plugins that rely on JavaScript frameworks, BlaBlaBlocks Tabs Block uses WordPress’s native Interactivity API.

That means:

Faster loading and rendering.

Better Core Web Vitals scores.

Seamless state management between editor and frontend.

5. Ready-to-Use Templates Save time with built-in templates. Choose from multiple tab styles (minimal, boxed, underlined, colored) and insert them with one click.

6. Works Everywhere Tabs Block is fully compatible with:

Block Themes (Full Site Editing)

Classic Themes using the Block Editor

Reusable Blocks and Block Patterns

Core blocks like Columns, Groups, and Cover
