# Large Text Cell Editor

Simple editor that uses the standard HTML `textarea`, allowing users to enter text shown over multiple lines.

## Enabling Large Text Cell Editor

Edit any cell in the grid below to see the Large Text Cell Editor.

#### Large Text Editor

```tsx
"use client";

import React, {
  useCallback,
  useMemo,
  useRef,
  useState,
  StrictMode,
} from "react";
import { createRoot } from "react-dom/client";
import { AgGridReact, AgGridProvider } from "ag-grid-react";
import {
  ClientSideRowModelModule,
  ColDef,
  ColGroupDef,
  GridApi,
  GridOptions,
  LargeTextEditorModule,
  ModuleRegistry,
  enableDevValidations,
} from "ag-grid-community";

if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

const modules = [ClientSideRowModelModule, LargeTextEditorModule];

const data = Array.from(Array(20).keys()).map(() => {
  return {
    description:
      "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.",
  };
});

const GridExample = () => {
  const containerStyle = useMemo(() => ({ width: "100%", height: "100%" }), []);
  const gridStyle = useMemo(() => ({ height: "100%", width: "100%" }), []);
  const [rowData, setRowData] = useState<any[]>(data);
  const [columnDefs, setColumnDefs] = useState<ColDef[]>([
    {
      headerName: "Large Text Editor",
      field: "description",
      cellEditor: "agLargeTextCellEditor",
      cellEditorPopup: true,
    },
  ]);
  const defaultColDef = useMemo<ColDef>(() => {
    return {
      flex: 1,
      editable: true,
    };
  }, []);

  return (
    <AgGridProvider modules={modules}>
      <div style={containerStyle}>
        <div style={gridStyle}>
          <AgGridReact
            rowData={rowData}
            columnDefs={columnDefs}
            defaultColDef={defaultColDef}
          />
        </div>
      </div>
    </AgGridProvider>
  );
};

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

[Live example: Large Text Editor](https://www.ag-grid.com/examples/provided-cell-editors-large-text/large-text-editor/reactFunctionalTs)

Enabled with `agLargeTextCellEditor` and configured with `ILargeTextEditorParams`.

```js
columnDefs: [
    {
        cellEditor: 'agLargeTextCellEditor',
        cellEditorPopup: true,
        cellEditorParams: {
            maxLength: 100
        }
        // ...other props
    }
]
```

## Customisation

### Editor Size

The width and height of the Large Text Cell Editor can be customised. Edit any cell in the grid below to see the editor displayed with a modified size.

#### Large Text Editor Cols and Rows

```tsx
"use client";

import React, {
  useCallback,
  useMemo,
  useRef,
  useState,
  StrictMode,
} from "react";
import { createRoot } from "react-dom/client";
import { AgGridReact, AgGridProvider } from "ag-grid-react";
import {
  ClientSideRowModelModule,
  ColDef,
  ColGroupDef,
  GridApi,
  GridOptions,
  ILargeTextEditorParams,
  LargeTextEditorModule,
  ModuleRegistry,
  enableDevValidations,
} from "ag-grid-community";

if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

const modules = [ClientSideRowModelModule, LargeTextEditorModule];

const data = Array.from(Array(20).keys()).map(() => {
  return {
    description:
      "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.",
  };
});

const GridExample = () => {
  const containerStyle = useMemo(() => ({ width: "100%", height: "100%" }), []);
  const gridStyle = useMemo(() => ({ height: "100%", width: "100%" }), []);
  const [rowData, setRowData] = useState<any[]>(data);
  const [columnDefs, setColumnDefs] = useState<ColDef[]>([
    {
      headerName: "Large Text Editor",
      field: "description",
      cellEditor: "agLargeTextCellEditor",
      cellEditorPopup: true,
      cellEditorParams: {
        rows: 15,
        cols: 50,
      } as ILargeTextEditorParams,
    },
  ]);
  const defaultColDef = useMemo<ColDef>(() => {
    return {
      flex: 1,
      editable: true,
    };
  }, []);

  return (
    <AgGridProvider modules={modules}>
      <div style={containerStyle}>
        <div style={gridStyle}>
          <AgGridReact
            rowData={rowData}
            columnDefs={columnDefs}
            defaultColDef={defaultColDef}
          />
        </div>
      </div>
    </AgGridProvider>
  );
};

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

[Live example: Large Text Editor Cols and Rows](https://www.ag-grid.com/examples/provided-cell-editors-large-text/large-text-editor-cols-rows/reactFunctionalTs)

To customise the size, there are two options:

- `cols`: The average number of characters displayed.
- `rows`: The number of lines of text displayed.

```js
columnDefs: [
    {
        cellEditor: 'agLargeTextCellEditor',
        cellEditorPopup: true,
        cellEditorParams: {
            rows: 15,
            cols: 50
        }
        // ...other props
    }
]
```
