Which pattern allows users to select an item from a grid to view more details in place of the grid?

The pattern that allows users to select an item from a grid to view more details in place of the grid is the drilldown. This approach provides an interactive user experience where, upon clicking an item within the grid, users are presented with a more detailed view specific to that item, often replacing the grid itself. This method is effective for maintaining context while providing in-depth information without cluttering the interface or overwhelming the user with data.

In scenarios where a grid is used to display multiple items, the drilldown pattern enhances usability by allowing users to focus on a single item without navigating away from their original location. This feature is particularly useful in applications dealing with extensive datasets, helping users to seamlessly transition from an overview to specific details while retaining the ease of navigation within the application.

Other patterns mentioned do not provide the same functionality. For instance, while "cards as buttons" can offer user interaction, they don't typically focus on item selection from a grid context. "Grid with detail view" might imply a layout where details are shown beside a grid rather than in place of it, and "breadcrumbs" are primarily used for navigation rather than item selection and detail expansion.
