Important Functionality Fields added to the field set will respect the required option as designated by field set or field metadata and not the page layout. ## Customize Fields Fields can be added to the sections that allow customization. For this example, let’s place the **Payment Processing Fee** field in the Event Details section. 1. Open the Event Builder. 2. Select an existing Event or create a new one. 3. Scroll down to the Event Details section. 4. Click **click here**. ![EVBuilder_EventDetails](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/EVBuilder_EventDetails.png) 5.
