I have built a zend form element for html content (general notes).

```
class Sistema_Form_Note extends Zend_Form_Element_Xhtml {

    public $helper = 'formNote';

    public function isValid($value){
        return true;
    }

}

```

It's working fine however it goes as a field and when I go to insert the post data on my database, the index note element appears.

```
POST array('name' => 'John'
  'note1' => ...); 

```

How could I remove it without using the `removeElement()` method on the controller? Is there any way to tell on the class it shouldn't be a "db field"?

Thanks
