*

* $attributes or $options for the different **type** methods can be included in `$options` for input().i
* Additionally, any unknown keys that are not in the list below, or part of the selected type's options
* will be treated as a regular html attribute for the generated input.
*
* - `type` - Force the type of widget you want. e.g. `type => 'select'`
* - `label` - Either a string label, or an array of options for the label. See FormHelper::label().
* - `div` - Either `false` to disable the div, or an array of options for the div.
* See HtmlHelper::div() for more options.
* - `options` - For widgets that take options e.g. radio, select.
* - `error` - Control the error message that is produced. Set to `false` to disable any kind of error reporting (field
* error and error messages).
* - `errorMessage` - Boolean to control rendering error messages (field error will still occur).
* - `empty` - String or boolean to enable empty select box options.
* - `before` - Content to place before the label + input.
* - `after` - Content to place after the label + input.
* - `between` - Content to place between the label + input.
* - `format` - Format template for element order. Any element that is not in the array, will not be in the output.
* - Default input format order: array('before', 'label', 'between', 'input', 'after', 'error')
* - Default checkbox format order: array('before', 'input', 'between', 'label', 'after', 'error')
* - Hidden input will not be formatted
* - Radio buttons cannot have the order of input and label elements controlled with these settings.

/**
* Returns a formatted SELECT element.
*
* ### Attributes:
*
* - `showParents` - If included in the array and set to true, an additional option element
* will be added for the parent of each option group. You can set an option with the same name
* and it's key will be used for the value of the option.
* - `multiple` - show a multiple select box. If set to 'checkbox' multiple checkboxes will be
* created instead.
* - `empty` - If true, the empty select option is shown. If a string,
* that string is displayed as the empty element.
* - `escape` - If true contents of options will be HTML entity encoded. Defaults to true.
* - `value` The selected value of the input.
* - `class` - When using multiple = checkbox the class name to apply to the divs. Defaults to 'checkbox'.
* - `disabled` - Control the disabled attribute. When creating a select box, set to true to disable the
* select box. When creating checkboxes, `true` will disable all checkboxes. You can also set disabled
* to a list of values you want to disable when creating checkboxes.
*
* ### Using options
*
* A simple array will create normal options:
*
* ```
* $options = array(1 => 'one', 2 => 'two);
* $this->Form->select('Model.field', $options));
* ```
*
* While a nested options array will create optgroups with options inside them.
* ```
* $options = array(
* 1 => 'bill',
* 'fred' => array(
* 2 => 'fred',
* 3 => 'fred jr.'
* )
* );
* $this->Form->select('Model.field', $options);
* ```
*
* In the above `2 => 'fred'` will not generate an option element. You should enable the `showParents`
* attribute to show the fred option.
*
* If you have multiple options that need to have the same value attribute, you can
* use an array of arrays to express this:
*
* ```
* $options = array(
* array('name' => 'United states', 'value' => 'USA'),
* array('name' => 'USA', 'value' => 'USA'),
* );
* ```
*
* @param string $fieldName Name attribute of the SELECT
* @param array $options Array of the OPTION elements (as 'value'=>'Text' pairs) to be used in the
* SELECT element
* @param array $attributes The HTML attributes of the select element.
