(Laravel)我可以直接将dropdown值传递给控制器方法吗？

<form action="{{ route('controller.method') }}" method="POST">
    @csrf
    <select name="dropdown">
        <option value="value1">Option 1</option>
        <option value="value2">Option 2</option>
        <option value="value3">Option 3</option>
    </select>
    <button type="submit">Submit</button>
</form>

Route::post('/submit', 'Controller@method')->name('controller.method');

public function method(Request $request)
{
    $dropdownValue = $request->input('dropdown');
    // 处理传递过来的值
}
