Content Blocks Builder

Content Blocks Builder (CBB) helps you create custom blocks, variations, styles, and patterns — directly in the Block Editor without touching a code editor.

The WordPress Block Editor (Gutenberg) is a solid foundation for building websites. But when you need more specific layouts or custom functionality not available in default blocks, you’re often forced to write custom code or rely on bloated third-party plugins.

CBB solves this by letting you visually group core or third-party blocks into flexible container blocks — right inside the native Block Editor. These container blocks support native features like typography, spacing, colors, borders, plus advanced features from CBB that help you build layouts like responsive grid, slider/carousel, toggle/accordion, modal/off-canvas/popover, background effects all without writing a single line of code.

You can also build repeater blocks to display repeatable content — similar to ACF repeater field type, but entirely block-based and visual.

The ultimate goal of CBB is to help you build complex layouts — all with core blocks, all visually, and fully compatible with any Gutenberg-ready theme.
No React. No PHP. No lock-in. No clutter. No bloat. Developer-friendly.

• Pre-built library: A library of pre-built blocks, variations, styles, and patterns. This library is not bundled with CBB; only items you import appear on your site.
• CBB are built with vanilla JS and CSS. It only depends on SwiperJs for the carousel functionality, — and even then, the script and styles are loaded only if the carousel layout is used.

Practical features you can build with CBB

• Carousel layouts: Ideal for creating banner slider, posts carousel, gallery, carousel of features or other repeating content, etc. CBB provides one of the best way to create a carousel layout in Gutenberg. Built on top of the popular SwiperJs carousel script, it supports extensive customization. CBB Pro enables you to create entrance effects, advanced slide effects with effect builder, and further customization like slides per breakpoint, pagination, navigation, and synced carousels.
• Responsive grid layouts: Perfect for creating equal column grid, mosaic grid, bento grid, posts grid, grid of features or other repeating content, etc. CBB provides the easiest but most flexible and robost grid layout based on CSS Grid layout. You can customize template columns, grid gaps, size, and location for each grid item.
• Accordion layouts: Good for creating FAQ page, navigations, long features or specications.
• Blog page design, magazine layout, post grid, post carousel; Work with any post types.
• Modal, off-canvas, popover, toggle content: Great for creating popups, notification bars, toggle menu, toggle search box, hamburger menu, popover, show/hide content, etc. CBB Pro allows you to add a custom entrance animation effect, control when popups appear with delay options, trigger them on scroll to elements or exit intent, and remember when a popup has been closed.
• Sticky content: Great for fixed/sticky header, footer, floating elements, sticky sidebar. CBB Pro enables you to style blocks based on their stuck state and make blocks sticky only when scrolling up.

For dynamic data, we recommend using the Meta Field Block plugin. It’s the best way to display dynamic data.
