Yes. Have your decorator extend Zend_Form_Decorator_Abstract, and
make sure that the decorator is in one of the prefix paths you set --
then you can use it just like your other decorators.
So, for instance, 'my_decorator' is a bad class name as it (a) doesn't
follow Zend coding standards, and (b) tells nothing about what it does.
>From what you say, it sounds like it's a submit button decorator -- so
let's call it 'My_Decorator_Submit'. Place it in
'My/Decorator/Submit.php' somewhere in your include_path.
Then, tell the form about the path:
$this->addElementPrefixPath('My_Decorator', 'My/Decorator/', 'decorator');
When you add the decorator, you can then add it like other decorators:
array(
'decorator' => 'Submit',
'options' => array('numColumns' => value, 'placement' => value),
)

Good.
