Adobe Pro needs to have a feature to create expandable drop down lists. I have seen it in other products, but it fits well with the PDF Pro.

I would like to be able to create easy drop down check lists, divided by topic, so the user can expand the form in the areas they need. This will reduce time for the customer to have to scroll through the document to find what they are looking for and will increase the functionality of the document.

I would like it to contain a plus box and minus box, so people can expand and retract the document if sections do not apply to what they need.
