zinio | command line tool removes DRM from magazines

My end goal is to create a series of individual elements based on a JSON file I am working with is below. What I was hoping to do to use the keys of each object as an in a different select element. For instance, the top level would be: Admin Combined Services App ...

Then the next level would be a distinct element with all of Admin's keys, a select for all of Admin's key's keys, etc. I've given this more than a few attempts but I can't quite wrap my head around recursion. Ideally I want to pre-generate the select statements so I can pul them up based on the top-level menu. Any suggestions? I'm totally open to the possibility that my approach is flawed. Ideally I'd like to avoid external libraries, and I am unfortunately stuck with JSON for this. I realize that a DB would solve this in a heartbeat.
