Reuse a Block across Cubes

A shared block is content that lives in one place and appears in many cubes. Edit it once and every cube using it changes.

Good candidates are things that are genuinely the same everywhere and change occasionally:

  • A shipping or returns promise.
  • A newsletter signup.
  • A seasonal campaign card you want on many products.

Surveys have their own group in the library — see Add a survey.

If the content should differ per cube even slightly, do not share it — copy it instead.

  1. Open Shared blocks in Admin.

  2. Create the block and write its content.

  3. In any cube, add it from the block library on the Versions tab.

If a block already lives on one cube and you want it reused, promote it.

On that cube’s Blocks tab, choose Promote to shared block. Rubikc copies the block into Shared blocks, puts the shared copy on every version of this cube that used the original, and removes the cube’s own copy.

Shared blocks have no unpublished state. If the block is on a version, shoppers see the shared copy.

That is the point of them, and it is also the risk. A shared block on fifty cubes is a fast way to update fifty cubes and a fast way to break them.

Removing a shared block from a cube affects only that cube. Deleting the shared block itself affects all of them.
