# TextField

`TextField` lets user enter a text data into a boxed field. It can sometimes contain related information or controls.

<Canvas>
  <Story id="components-componentlibrary-textfield--default-story" />
</Canvas>

## Props

The `TextField` accepts all props below as well as all [Box](/docs/components-ui-box--default-story#props) component props

<ArgsTable of={TextField} />

### Size

Use the `size` prop to set the height of the `TextField`.

Possible sizes include:

- `sm` 32px
- `md` 40px
- `lg` 48px

Defaults to `md`

<Canvas>
  <Story id="components-componentlibrary-textfield--size-story" />
</Canvas>

```jsx
import { Size } from '../../../helpers/constants/design-system';
import { TextField } from '../../component-library';

<TextField size={Size.SM} />
<TextField size={Size.MD} />
<TextField size={Size.LG} />
```

### Type

Use the `type` prop to change the type of input.

Possible types include:

- `text`
- `number`
- `password`

Defaults to `text`.

<Canvas>
  <Story id="components-componentlibrary-textfield--type" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField type="text" /> // (Default)
<TextField type="number" />
<TextField type="password" />
```

### Truncate

Use the `truncate` prop to truncate the text of the the `TextField`. Defaults to `true`.

<Canvas>
  <Story id="components-componentlibrary-textfield--truncate" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField truncate />; // truncate is set to `true` by default
<TextField truncate={false} />;
```

### Start accessory End Accessory

Use the `startAccessory` and `endAccessory` props to add components such as icons or buttons to either side of the `TextField`.

<Canvas>
  <Story id="components-componentlibrary-textfield--start-accessory-end-accessory" />
</Canvas>

```jsx
import { Color, IconColor, SIZES, DISPLAY } from '../../../helpers/constants/design-system';
import { TextField, Icon, IconName, ButtonIcon } from '../../component-library';

<TextField
  placeholder="Search"
  startAccessory={
    <Icon
      color={IconColor.iconAlternative}
      name={IconName.Search}
    />
  }
/>

<TextField
  placeholder="Public address (0x), or ENS"
  endAccessory={
    <ButtonIcon
      iconName={IconName.ScanBarcode}
      ariaLabel="Scan QR code"
      iconProps={{ color: IconColor.primaryDefault }}
    />
  }
/>

<TextField
  placeholder="Enter amount"
  type="number"
  truncate
  startAccessory={<SelectTokenComponent />}
  endAccessory={<TokenValueInUSDComponent />}
/>

<TextField
  placeholder="Public address (0x), or ENS"
  truncate
  startAccessory={<AvatarAccount />}
  endAccessory={
    isAddressValid && (
      <Icon
        name={IconName.Check}
        color={IconColor.successDefault}
      />
    )
  }
/>
```

### Input Ref

Use the `inputRef` prop to access the ref of the `<input />` html element of `TextField`. This is useful for focusing the input from a button or other component.

<Canvas>
  <Story id="components-componentlibrary-textfield--input-ref" />
</Canvas>

```jsx
import { Button, TextField } from '../../component-library';

const inputRef = useRef(null);
const [value, setValue] = useState('');
const handleOnClick = () => {
  inputRef.current.focus();
};
const handleOnChange = (e) => {
  setValue(e.target.value);
};

<TextField
  inputRef={inputRef}
  value={value}
  onChange={handleOnChange}
/>
<Button marginLeft={1} onClick={handleOnClick}>
  Edit
</Button>
```

### Input Component

Use the `InputComponent` prop change the component used for the input element. This is useful for replacing the base input with a custom input while retaining the functionality of the `TextField`.

Defaults to the [Text](/docs/components-componentlibrary-text--default-story) component

To function fully the custom component should accept the following props:

- `aria-invalid`
- `as`
- `autoComplete`
- `autoFocus`
- `backgroundColor`
- `defaultValue`
- `disabled`
- `focused`
- `id`
- `margin`
- `maxLength`
- `name`
- `onBlur`
- `onChange`
- `onFocus`
- `padding`
- `paddingLeft`
- `paddingRight`
- `placeholder`
- `readOnly`
- `ref`
- `required`
- `value`
- `variant`
- `type`

<Canvas>
  <Story id="components-componentlibrary-textfield--input-component" />
</Canvas>

```jsx
import { TextField, Icon, IconName } from '../../component-library';

// should map the props to the custom input component
const CustomInputComponent = () => <div>{/* Custom input component */}</div>;

const TextFieldCustomInput = (args) => (
  <TextField
    size={SIZES.LG}
    InputComponent={CustomInputComponent}
    startAccessory={
      <Icon color={IconColor.iconAlternative} name={IconName.Wallet} />
    }
  />
);
```

### Auto Complete

Use the `autoComplete` prop to set the autocomplete html attribute. It allows the browser to predict the value based on earlier typed values.

<Canvas>
  <Story id="components-componentlibrary-textfield--auto-complete" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField type="password" autoComplete />;
```

### Auto Focus

Use the `autoFocus` prop to focus the `TextField` during the first mount

To view story see [Canvas tab](/story/components-componentlibrary-textfield--auto-complete). Removing it from docs because created annoying reading experience 😁

```jsx
import { TextField } from '../../component-library';

<TextField autoFocus />;
```

### Default Value

Use the `defaultValue` prop to set the default value of the `TextField`

<Canvas>
  <Story id="components-componentlibrary-textfield--default-value" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField defaultValue="default value" />;
```

### Disabled

Use the `disabled` prop to set the disabled state of the `TextField`

<Canvas>
  <Story id="components-componentlibrary-textfield--disabled" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField disabled />;
```

### Error

Use the `error` prop to set the error state of the `TextField`

<Canvas>
  <Story id="components-componentlibrary-textfield--error-story" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField error />;
```

### Max Length

Use the `maxLength` prop to set the maximum allowed input characters for the `TextField`

<Canvas>
  <Story id="components-componentlibrary-textfield--max-length" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField maxLength={10} />;
```

### Read Only

Use the `readOnly` prop to set the `TextField` to read only. When `readOnly` is true `TextField` will not have a focus state.

<Canvas>
  <Story id="components-componentlibrary-textfield--read-only" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

<TextField readOnly />;
```

### Required

Use the `required` prop to set the `TextField` to required. Currently there is no visual difference to the `TextField` when required.

<Canvas>
  <Story id="components-componentlibrary-textfield--required" />
</Canvas>

```jsx
import { TextField } from '../../component-library';

// Currently no visual difference
<TextField required />;
```
