JavaScript Decision Tree tool

My goal has been to make a JavaScript Decision Tree tool as a new content module for our next site redesign.

It needs to work such that the same piece of JavaScript can be utilised without modification for any decision tree tool we build on the site, with a very simply-defined markup structure,

So I’ve been self-administering repeated doses of headdesk/facepalm over the last couple of days, but I came back today after a Friday lunch (you know what I mean) and found a solution. It’s not pretty, with at least two nested ‘for’ loops, but it works.

I’ve created a JSFiddle of it, so you can take a look at it, modify it, laugh at it, etc.
Open it in JSFiddle or see it embedded below:
