# Row Selection

Configure the grid to allow users to select rows by clicking them, focusing a row and pressing `␣ Space` or via API.

## Enabling Row Selection

Row selection is configured with the `rowSelection` grid property. Setting `rowSelection.mode` to either `'multiRow'` or `'singleRow'` will allow you to select rows by clicking, focusing a row and pressing `␣ Space`, or via the selection API.

```jsx
const rowSelection = useMemo(() => { 
	return {
        mode: 'singleRow',
    };
}, []);

<AgGridReact rowSelection={rowSelection} />
```

The following example illustrates a basic row selection configuration. Use the select control to choose the default single row or multi-row configuration.

See detailed documentation on the two row selection modes:

- [Single Row Selection](https://www.ag-grid.com/react-data-grid/row-selection-single-row/)
- [Multi-Row Selection](https://www.ag-grid.com/react-data-grid/row-selection-multi-row/)

#### Enabling Row Selection

## Row Selection with Enterprise Features

Row selection can be used when using row grouping, tree data and the server-side row model. See the respective sections of the documentation:

- [Row Group Selection](https://www.ag-grid.com/react-data-grid/grouping-row-selection/)
- [Tree Data Selection](https://www.ag-grid.com/react-data-grid/tree-data-selection/)
- [Server-Side Row Model Selection](https://www.ag-grid.com/react-data-grid/server-side-model-selection/)
