What layout format helps in displaying hierarchical content efficiently in a user interface?

The Tree Grid layout format is specifically designed to display hierarchical content effectively in a user interface. This layout combines the features of a tree structure, which allows for the representation of parent-child relationships, with the ability to show data in a tabular format.

Using a Tree Grid, users can easily expand or collapse nodes to view or hide sub-items, making it particularly useful for displaying data that has multiple levels of related information, such as organizational charts, categories and subcategories in a product catalog, or file directory structures.

This layout format enhances the user experience by providing a clear visual representation of how data elements are related, allowing for better navigation and understanding of complex data sets. Other formats like Grid, Column, and Inline layouts are better suited for different types of information presentation, but they do not inherently support the hierarchical representation that the Tree Grid does.
