# TextArea

```gistui
root = Form("feedback", TextArea("notes", "What could be better?", placeholder:"Tell us more…", rows:4, maxLength:500, hint:"Up to 500 characters"))
```

## Signature

This is the line a model reads in the system prompt.

```gistui
TextArea(name, label, placeholder:str, value:str, rows:num, minLength:num, maxLength:num, error:str, bind:$var, size:Size, hint:str, required)
```

- **Group:** Forms
- **Children:** No
- **Positional arguments:** `name`, `label` (a trailing `?` means it may be left out)

## Props

|---|---|---|---|

| `label` | string | positional, required |  |
| `placeholder` | string | named: `placeholder:…` |  |
| `value` | string | named: `value:…` |  |
| `rows` | number | named: `rows:…` | Default `4`. |
