Container Extension for TYPO3

The Container Extension extends TYPO3 with a powerful yet simple concept: container content elements.

A container is a content element that can hold other content elements.

This makes it easy to create layout sub-structures directly in the backend—such as two-column sections, card grids, or nested content areas.

In 2025, our extension won the TYPO3 Award for “Best TYPO3 Extension“.

A huge thank you and congratulations to our developer, Achim Fritz! We are proud to build tools that strengthen TYPO3 for everyone.

How it works

Each container type defines content areas (for example, left/right column).

Editors can put any content elements into these content areas—no technical knowledge required.

Rendering happens entirely within your project’s site package:

The result: maximum flexibility, minimal complexity.

Define your own container types using TCA configuration.
Fully Core-compliant—no CType overrides.
Clean markup thanks to dedicated Fluid templates.
Nested containers supported.
Works seamlessly with Fluid DataProcessors, ViewHelpers, and custom layout logic.

Advantage: Full control over structure and markup—while keeping content editing safe and intuitive.

Visual clarity: Content is grouped logically and clearly displayed in the backend.
Flexible layouts: Design individual page sections without technical knowledge.
Safe boundaries: Editors can only add content where it’s allowed (when the TYPO3 extension “content_defender” is installed).
Consistent design: Containers define the layout rules—editors fill the content.

Compared to older solutions like Gridelements or Flux, Container works directly with TYPO3 Core mechanisms. This makes it:

The extension is actively maintained, fully compatible with current TYPO3 versions, and used in many enterprise projects.
