Which type of layout repeats its entries vertically in rows?

The correct answer is that a layout that repeats its entries vertically in rows is a Row Repeat. This layout is specifically designed to allow data or components to be displayed in a vertical arrangement, where each entry appears in an individual row. This format is particularly useful for organizing data in a way that is easy to read and navigate vertically.

In a Row Repeat, you can dynamically populate multiple entries based on the data source, and each entry will be visually aligned in separate rows. This is especially advantageous when displaying long lists of items or records, where a vertical arrangement enhances usability and comprehension.

The other layout options like Tab Repeat, Column Repeat, and Grid have different structural orientations. A Tab Repeat typically organizes content into tabs, facilitating navigation between different sets of data without a direct vertical stacking. A Column Repeat, in contrast, would allow data to be displayed in a series of columns rather than rows, which changes how users interact with the information. Lastly, a Grid layout organizes data in both rows and columns, allowing for more complex arrangements and interactions, but it does not specifically emphasize the vertical repetition of entries as a Row Repeat does.
