What should a developer set in the Title field to automatically populate it with the item's name in Sitecore?

To automatically populate the Title field with the item's name in Sitecore, a developer should use the $name token. This token specifically refers to the name of the item within Sitecore’s content tree. When set in the Title field, it dynamically pulls the item's actual name whenever the item is created or accessed. This functionality is particularly beneficial for maintaining consistency and reducing the need for manual entry, especially in scenarios where items are frequently created or duplicated.

Using other tokens, such as $title, $item, or $displayName, would not yield the desired result. The $title token signifies a custom title that may not necessarily reflect the item's name. The $item token could refer to the entire item object rather than a property like name, which isn't suitable for directly filling in the Title field. The $displayName token, conversely, often relates to how the item is represented in the user interface and may not match the item’s actual name. Thus, using the $name token is the most appropriate choice for this purpose.
