defmodule Surface.Components.Form.TextArea do
@moduledoc """
An input field that let the user enter a **multi-line** text.
Provides a wrapper for Phoenix.HTML.Form's `textarea/3` function.
All options passed via `opts` will be sent to `textarea/3`. Explicitly
defined properties like `value` and `class` can be set directly and will
override anything in `opts`.
## Examples
```
<TextArea form="user" field="summary" cols="5" rows="10" opts={autofocus: "autofocus"} />
```
