• 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'),
);

Parameters

string $fieldName

Name attribute of the SELECT

array $options optional array()

Array of the OPTION elements (as 'value'=>'Text' pairs) to be used in the SELECT element

array $attributes optional array()

The HTML attributes of the select element.

Returns

string
Formatted SELECT element
