| [Column](/engine/6000.7/script-reference/unityengine/uielements/gridautoflow/column.md)           | Items are placed by filling each column in turn, adding new columns as necessary.                                                                                                   |

| [Row](/engine/6000.7/script-reference/unityengine/uielements/gridautoflow/row.md)                 | Items are placed by filling each row in turn, adding new rows as necessary. This is the default.                                                                                    |
