label - Either a string label, or an array of options for the label. See FormHelper::label().
options - For widgets that take options e.g. radio, select.

empty - String or boolean to enable empty select box options.
nestedInput - Used with checkbox and radio inputs. Set to false to render inputs outside of label elements. Can be set to true on any input to force the input inside the label. If you enable this option for radio buttons you will also need to modify the default radioWrapper template.
templates - The templates you want to use for this input. Any templates will be merged on top of the already loaded templates. This option can either be a filename in /config that contains the templates you want to load, or an array of templates to use.
labelOptions - Either false to disable label around nestedWidgets e.g. radio, multicheckbox or an array of attributes for the label tag. selected will be added to any classes e.g. class => 'myclass' where widget is checked

Using options

A simple array will create normal options:

$options = [1 => 'one', 2 => 'two'];
$this->Form->select('Model.field', $options));

While a nested options array will create optgroups with options inside them.

$options = [
 1 => 'bill',
    'fred' => [
        2 => 'fred',
        3 => 'fred jr.'
    ]
];
$this->Form->select('Model.field', $options);

If you have multiple options that need to have the same value attribute, you can use an array of arrays to express this:

$options = [
    ['text' => 'United states', 'value' => 'USA'],
    ['text' => 'USA', 'value' => 'USA'],
];

string $fieldName: Name attribute of the SELECT
