jeffc2sky on "Enquiry/Contact form plug in with a responsive yes no drop down menu"

Hi Guys,
I am wondering if anyone knows of a contact/enquiry form plugin that allows me to have a new drop down menu open when the yes or no option is selected. I am currently using CF7 but no sure if this can be configured for what I need.
Of course I am no html/css genius hence the plug ins but any advice appreciated.
