Create Subcategory option in adobe acrobat pro

[Creatives Corner]

Hello,

I am trying to create form like this ( National Healthcare Achievers, 2015 | Nominate ). I am done with everything but i don't know how to create following functionality with adobe acrobat pro. Even any alternative solution will work too. But i need to distinguish every category. Kindly help.

Thanks
