Zend Linked or Dependent DropDowns

Does anyone knows how to properly make dependent dropdowns using the Zend Framework? I've 开发者_如何学Pythonfound several ways to do so, but none of them is using the framework features.

Dependent Dropdown: The options shown on the "B" , depends on the option selected on the "A" .

Thanks for your help, Best regards,

you could use the processAjax() method in the action. What do you mean by using the framework features?

This is currently no built in functionality for filtering selects in Zend Framework (v1.10).

The next best solution I came across was probably the Zend_Dojo_Form_Element_FilteringSelect but I don't like it.

Iim planning to write my own FilteringSelect component by integrating the standard ZF component with ajax or jquery... one day!
