The Multiple Forms extension for GravityView supports both [JOIN and UNION](https://www.gravitykit.com/joins-vs-unions/) operations. Union support was added in Multiple Forms 0.7.0 and requires GravityView 3.3.0 or newer.

## How joins and unions differ

A **join** matches related entries from different forms using a shared field value, like an email address or an ID, and displays them side by side in one row. A join makes each row wider, because it adds the second form’s columns to the first.

A **union** stacks complete entries from several forms into one list, with one row per entry and no shared field required. A union makes the list longer, because it adds the second form’s entries as extra rows.

Easier to see than to read? Our [joins and unions](https://www.gravitykit.com/joins-vs-unions/) page walks through both with animated examples, so you can watch a join widen a row and a union lengthen a list.

To set up a union, read [Using unions in Multiple Forms](https://www.gravitykit.com/docs/gravityview-pro/multiple-forms/using-unions-in-multiple-forms/).
