This example demonstrates the configuration of a Line Item Editor for Opportunity Products:
* **Parent:** Opportunity
* **Line Item:** OpportunityLineItem
* **Lookup:** PricebookEntry
{% endhint %}
1. Add the Related List Configurator to the Opportunity record page.
2. The configured Line Item button will appear in the related list section.
