${frame}[Video: anatomy of the Connector block](https://celestory-docs-videos.netlify.app/en/anatomie-bloc/connector.html)

![Connector](https://celestory-docs-illustrations.netlify.app/en/Connector_EN.svg)

The Connector block allows you to merge several paths in a graph to unify the flow towards a common scenario or to visually air out the graph by avoiding tangled connections.

It serves as a junction point to group logical branches or simplify the reading of complex flows.

## 📥 Entries

- in (Flow): End point of the application flow. Allows you to connect several outputs from previous blocks to group them into a single input.

## 📤 Outings

- out (Flow): Logical continuity of the flow. Passage through the connector is instantaneous and transparent to the end user.

## 💡 Example of use

Scenario: Group paths after multiple choice

1. A Choices block offers three different options to the user.
1. Each option leads to a different block (eg: Show a message, Modify a variable, Start an animation).
1. Place a Connector block after these three blocks to group the flows.
1. Connect the outputs of the three blocks to the in input of the Connector.
1. The out output of the Connector can now be used to continue the common scenario (eg: Show an end screen).

## ⚙️ Technical Details

- Stream behavior: The block does not modify the data in the stream, it only serves as a transparent crossing point.
- Multiple input management: All inputs connected to in are treated as a single unified output source.
