    /**
     * 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 classname to apply to the divs. Defaults to 'checkbox'.
     *
     * ### 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
