# Using Lists as Input for Subflows in Parameters

In this documentation article, learn how to use Lists as Inputs for Sub-Flows in Parameters.

[Embedded content](https://www.youtube.com/embed/0zGAD-xqO9M?&wmode=opaque&rel=0)

To get started with this new feature, you must have a **Master Flow** ready, open a **Subflow** of this model.

To learn more about parameters, check out these documentation articles: [**Show Default Value for Subflow Parameters**](/docs/show-default-value-for-subflow-parameters)

Once you’ve opened your **Subflow model,** open the **Test Data & Automation tab** in the **header menu,** and then hit the **Variables option.**

This opens the **Test Data Variables window,** here you can add **Data Variables** to your model. You can also view and edit existing variables.

To use **Lists** as Input for **Subflow Parameters**, edit an existing variable or create a new one by hitting the **Add Variable button**, this will open the **Data Variable window.**

In the **Data Variable** window you can now select **List Variable** as your **Variable Type,** make sure you also provide some **List Values** and **tick the Expose as IN Flow Parameter box**, as shown below in our example:

Once you set up and **save** your **Data Variables**, head on over to your **Master Flow,** here you will be able to view your **Input Parameters** for your **Subflow.**

To view your parameters, **right-click** on your **Subflow** and select **Subflow Properties**, this will open the **Subflow Properties window**.

In the **Subflow Properties window,** open the **Input Parameters tab**, here you will find the data you previously set up as the **Data Variable** and can select from the **List Values** you created.
