Additionaly you should add you own InArray Validator in order to protect your db etc.

In Zend Framework 1 it looks like this:

$this->addElement('select', $name, array(
            'required' => true,
            'label' => 'Choose sth:',
            'filters' => array('StringTrim', 'StripTags'),
            'multiOptions' => $nestedArrayOptions,
            'validators' => array(
                array(
                    'InArray', true, array(
                        'haystack' => $flatArrayOptionsKeys,
                        'messages' => array(
                            Zend_Validate_InArray::NOT_IN_ARRAY => "Value not found"
                        )
                    )
                )
            )
        ));

Where $nestedArrayOptions is you multiOptions and $flatArrayOptionsKeys contains you all keys.
