Learn how to open the custom field list page of a standard or custom object via the Schema Visualizer.

Navigate to **Object manager entry** in the left navigation menu.

On the Object Manager page, click the **Schema Visualizer** tab. A canvas with Zuora Billing objects opens.

If the object you want to search does not belong to Zuora Billing, enable the corresponding product filter by clicking the product name in the upper left of the page. For example, if you want to create a custom field for the Payment Method object, enable the **Payment** product filter.

Hover your mouse over the object name on the canvas and then click the Edit icon *(edit gray icon)*. The custom field list page of this object opens.
