# Single Row Selection

Enable users to select a single row within a grid.

## Enabling Single Row Selection

To enable single row selection set `rowSelection.mode` to `'singleRow'`.

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

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

The example below uses this configuration to restrict selection to a single row

    <GridExample />
  </StrictMode>,
);
```

[Live example: Enabling Row Selection](https://www.ag-grid.com/examples/row-selection-single-row/enabling-row-selection/reactFunctionalTs/)

Deselect a row by clicking its checkbox. Alternatively, you can do this via the keyboard by focusing the row and pressing the `␣ Space` key.

## Removing Selection Checkboxes

To prevent any row selection checkboxes from being rendered, set `rowSelection.checkboxes` to `false`. You will also need to enable click selection by setting `enableClickSelection: true`.

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

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

[Live example: Disabling Checkboxes](https://www.ag-grid.com/examples/row-selection-single-row/removing-selection-checkboxes/reactFunctionalTs/)

> **Note**
>
> Setting `rowSelection.checkboxes` to the boolean `false` removes the checkboxes entirely. Passing a function instead keeps the checkboxes present and enables or disables them per row: a selectable row for which the function returns `false` shows a disabled checkbox rather than removing it.
>
> For rows where both `isRowSelectable` and `rowSelection.checkboxes` return `false`, checkboxes will be hidden, rather than disabled.

## Configure Selectable Rows

It is possible to specify which rows can be selected via the `rowSelection.isRowSelectable` callback function.

For instance if we only wanted to allow selection for rows where the 'year' property is less than 2007, we could implement the following:

```jsx
const rowSelection = useMemo(() => { 
	return {
        mode: 'singleRow',
        isRowSelectable: (rowNode) => rowNode.data ? rowNode.data.year < 2007 : false,
        hideDisabledCheckboxes: true
    };
}, []);

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

Rows for which `isRowSelectable` returns `false` cannot be selected at all, whether using the UI or the API.

#### Configuring Selectable Rows

```tsx
'use client';
import { useFetchJson } from './useFetchJson';
import React, { StrictMode, useMemo, useRef } from "react";
import { createRoot } from "react-dom/client";

import {
  ClientSideRowModelModule,
  RowSelectionModule,
  enableDevValidations,
} from "ag-grid-community";
import type { ColDef, RowSelectionOptions } from "ag-grid-community";
import { AgGridProvider, AgGridReact } from "ag-grid-react";

import "./styles.css";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

const modules = [RowSelectionModule, ClientSideRowModelModule];

const GridExample = () => {
  const grid = useRef<AgGridReact>(null);
  const defaultColDef = useMemo(
    () => ({
      flex: 1,
      minWidth: 100,
    }),
    [],
  );

  const columnDefs = useMemo<ColDef[]>(
    () => [
      { field: "athlete" },
      { field: "sport" },
      { field: "year", maxWidth: 120 },
    ],
    [],
  );

  const rowSelection = useMemo<RowSelectionOptions>(
    () => ({
      mode: "singleRow",
      hideDisabledCheckboxes: true,
      isRowSelectable: (node) => (node.data ? node.data.year < 2007 : false),
    }),
    [],
  );

  const { data, loading } = useFetchJson<IOlympicData>(
    "https://www.ag-grid.com/example-assets/small-olympic-winners.json",
  );

  function toggleHideCheckbox() {
    grid.current?.api.setGridOption("rowSelection", {
      mode: "singleRow",
      isRowSelectable: (node) => (node.data ? node.data.year < 2007 : false),
      hideDisabledCheckboxes: getCheckboxValue("#toggle-hide-checkbox"),
    });
  }

  return (
    <AgGridProvider modules={modules}>
      <div className="example-wrapper">
        <div className="example-header">
          <label>
            <span>Hide disabled checkboxes:</span>
            <input
              id="toggle-hide-checkbox"
              type="checkbox"
              defaultChecked
              onChange={toggleHideCheckbox}
            />
          </label>
        </div>
        <div id="myGrid" className="grid">
          <AgGridReact
            ref={grid}
            rowData={data}
            loading={loading}
            defaultColDef={defaultColDef}
            columnDefs={columnDefs}
            rowSelection={rowSelection}
          />
        </div>
      </div>
    </AgGridProvider>
  );
};

const root = createRoot(document.getElementById("root")!);
root.render(
  <StrictMode>
    <GridExample />
  </StrictMode>,
);

function getCheckboxValue(id: string): boolean {
  return document.querySelector<HTMLInputElement>(id)?.checked ?? false;
}
```

[Live example: Configuring Selectable Rows](https://www.ag-grid.com/examples/row-selection-single-row/configure-selectable-rows/reactFunctionalTs/)

Note this example uses `hideDisabledCheckboxes` to hide disabled checkboxes, which can be toggled on or off.

## Customising the Checkbox Column

The checkbox column may be customised in a similar way to any other column, by specifying its column definition in the `selectionColumnDef` grid option.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `selectionColumnDef` | `SelectionColumnDef` |  |  | Configure the selection column, used for displaying checkboxes. Note that due to the nature of this column, this type is a subset of `ColDef`, which does not support several normal column features such as editing, pivoting and grouping. |

The `SelectionColumnDef` allows for a great deal of customisation, including custom renderers, sorting, tooltips and more. The example below demonstrates the following configuration:

- allowing sorting using the default sort order (selected first) via the header menu
- changing the default width of the column
- allowing resizing
- adding some header tooltip text

```jsx
const selectionColumnDef = useMemo(() => { 
	return {
        sortable: true,
        resizable: true,
        width: 100,
        suppressHeaderMenuButton: false,
        headerTooltip: 'Checkboxes indicate selection',
    };
}, []);

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

## Enable Click Selection & Deselection

The `rowSelection.enableClickSelection` property configures whether a row's selection state will be impacted when the row is clicked.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `enableClickSelection` | `boolean \| 'enableDeselection' \| 'enableSelection'` |  | `false` | Modifies the selection behaviour when clicking a row. Choosing `'enableSelection'` allows selection of a row by clicking the row itself. Choosing `'enableDeselection'` allows deselection of a row by CTRL-clicking the row itself. Choosing `true` allows both selection of a row by clicking and deselection of a row by CTRL-clicking. Choosing `false` prevents rows from being selected or deselected by clicking. |

This is typically used when [Checkbox Selection](#removing-selection-checkboxes) is disabled, though both can be enabled simultaneously if desired. Click-selection and deselection can be enabled by setting `enableClickSelection` to `true`, otherwise they may be enabled separately using the values `'enableSelection'` and `'enableDeselection'`.

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

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

The example below demonstrates the three possible configurations for this property, as well as the behaviour when it is disabled. Click a row to select it, or `^ Ctrl`-click a row to deselect it. Use the select element to switch between modes.

## API Reference

See the full list of configuration options available in `'singleRow'` mode.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `mode` | `'singleRow'` |  |  | 'singleRow' |
| `enableClickSelection` | `boolean \| 'enableDeselection' \| 'enableSelection'` |  | `false` | Modifies the selection behaviour when clicking a row. Choosing `'enableSelection'` allows selection of a row by clicking the row itself. Choosing `'enableDeselection'` allows deselection of a row by CTRL-clicking the row itself. Choosing `true` allows both selection of a row by clicking and deselection of a row by CTRL-clicking. Choosing `false` prevents rows from being selected or deselected by clicking. |
| `checkboxes` | `boolean \| CheckboxSelectionCallback` |  | `true` | Set to `true` or return `true` from the callback to render a selection checkbox. |
| `checkboxLocation` | `CheckboxLocation` |  | `'selectionColumn'` | Configure where checkboxes are displayed. Choosing `'selectionColumn'` displays checkboxes in a dedicated selection column. Choosing `'autoGroupColumn'` displays checkboxes in the autoGroupColumn. This applies to row checkboxes and header checkboxes. |
| `hideDisabledCheckboxes` | `boolean` |  | `false` | Set to `true` to hide a disabled checkbox when row is not selectable and checkboxes are enabled. |
| `isRowSelectable` | `IsRowSelectable` |  |  | Callback to be used to determine which rows are selectable. By default rows are selectable, so return `false` to make a row non-selectable. |
| `copySelectedRows` | `boolean` |  | `false` | When enabled and a row is selected, the copy action should copy the entire row, rather than just the focused cell |
| `enableSelectionWithoutKeys` | `boolean` |  | `false` | Set to `true` to allow (possibly multiple) rows to be selected and deselected using single click or touch. |
| `masterSelects` | `'self' \| 'detail'` |  | `'self'` | Determines the selection behaviour of master rows with respect to their detail cells. When set to `'self'`, selecting the master row has no effect on the selection state of the detail row. When set to `'detail'`, selecting the master row behaves the same as the header checkbox of the detail grid. |

## Row Selection with Enterprise Features

Row selection works with row grouping, tree data, and the server-side row model. See the relevant documentation sections:
