[fw-general] Add class to a multi option in Zend_Dojo_Form_Element_FilteringSelect

[Ralf Eggert]

Hi,

I would like to set a css class for some of the options in a Dojo
FilteringSelect form element. Is this possible with Zend_Dojo? And if
not, is it somehow possible with Dojo FilteringSelect at all?

Thanks,

Ralf
