Fill in Custom Field Details
Enter the Field Name, select a Group (or create a new one), and add Option Names and Values if applicable (e.g., for dropdowns or radios).
Save and Verify Placement
Click Save to create the custom field.
For Contact Custom Fields, go to a contact record to see the new field. For Opportunity Custom Fields, go to an opportunity card to see the field under “Opportunity Details.”
