<!-- With form field (errors are pulled from the field automatically) -->
<.input field={@form[:email]} type="email" label="Email Address" />

<!-- Select -->
<.input
  type="select"
  name="country"
  label="Country"
  options={[{"United States", "us"}, {"Canada", "ca"}, {"Mexico", "mx"}]}
  prompt="Select a country"
/>

<!-- Textarea -->
<.input type="textarea" name="message" label="Message" rows={5} />

<!-- Checkbox -->
<.input type="checkbox" name="terms" label="I accept the terms" />

<!-- Password -->
<.input type="password" name="password" label="Password" />

<!-- Number -->
<.input type="number" name="quantity" label="Quantity" min={1} max={100} />
```

### Error Component

```heex
<.error :for={msg <- @form[:email].errors}>
  {translate_error(msg)}
</.error>
```

## Common Patterns

### Simple Form

```heex
<.form for={@form} phx-submit="save">
  <.input field={@form[:name]} type="text" label="Name" />
  <.input field={@form[:email]} type="email" label="Email" />
  <.input field={@form[:password]} type="password" label="Password" />
  <.input field={@form[:role]} type="select" label="Role" options={@roles} />
  <.input field={@form[:bio]} type="textarea" label="Bio" />
  <.input field={@form[:newsletter]} type="checkbox" label="Subscribe to newsletter" />
  <.button type="submit">Save</.button>
</.form>
```

### Dynamic Form Fields

```heex
<.input
  :for={{field, opts} <- @fields}
  field={@form[field]}
  type={opts.type}
  label={opts.label}
  options={opts[:options]}
/>
```

## Note

For more specialized input components with additional styling options, consider:
`text_field`, `email_field`, `password_field`, `number_field`, `textarea_field`, `native_select` (styled versions of each type).

`input` gives basic Phoenix form integration; the specialized field components offer more customization.
