Layout Builder Block Limit

Layout Builder Block Limit lets site builders set a maximum number of blocks allowed per region in Layout Builder layouts. When a region reaches its limit, the "Add block" button is hidden, preventing editors from adding more.

Features

• Set per-region block limits scoped to a specific entity type and bundle (e.g. limit the content region on node/article to 3 blocks)
• Works with both default layouts and per-entity layout overrides
• Simple admin UI at Administration > Configuration > Layout Builder Block Limit
• No interference with the Layout Builder UI beyond hiding the Add block button when the limit is reached

Post-Installation

After enabling the module, go to Administration > Configuration > Content authoring > Layout Builder Block Limit to add limits. Each limit is defined by:

• Entity type — machine name (e.g. node)
• Bundle — machine name (e.g. article)
• Region — Layout Builder region machine name (e.g. content)
• Maximum blocks — the maximum number of blocks allowed in that region

Limits take effect immediately in the Layout Builder UI. Remove any limit from the same settings page.

Additional Requirements

• Drupal core Layout Builder module (included in Drupal core ^10.3 || ^11)
