Dynamic Categories

I have finished the dynamic category drop-down menu. If you take a look you will see the 4 arrays which the database will populate with its code, I have filled it out for testing purposes. below the arrays, you will see the main sub-array which holds all other sub-arrays. the rest of the code is completely dynamic and everything will recalculate based on how many sub-categories are in each array. the one thing I have not gotten on to do is the plus/minus since the in-browser programming language doesn't support it so I will need to transfer my code into a different software for that.
