Conditional format - new field based on a selection from a Drop-down menu in another field PDF Form

I am looking to create a PDF form from an existing Excel workbook. 

The form contains several drop-down fields, with Responses "Yes", "No" or "Yes, please specify", "N/A"

I am looking to set up the form so that if a user selects the "Yes" or "Yes, please specify" option in some of the drop downs, to have a number of other fields come up. (If the users choses "No" or "N/A" I want no other options to be present).

For example, below I have a drop down menu in Cell H10 with options "Yes, Please specify" and "N/A".

When "Yes, please specify" is selected:

- cell I10 and J&K10 appear. I10 is populated with "Please specify" and J&K10 is blank for the user to fill.

- cells B-G11 (merged) appear and is populated with "If this is needed select response.?"; cell H11 appears with a drop down menu with options "Yes", "No"

If "N/A" is selected in cell H10 - Cell I10, J&K10, B-G11 and H11 do not appear
