/**
* Create a select box field.
*
* @param string $name
* @param array $list
* @param string $selected
* @param array $options
* @return string
*/
public function select($name, $list = array(), $selected = null, $options = array());

echo Form::select('size', array('key' => 'value'), 'default', array('id' => 'ID_HERE'));
