## Simple 2 way constrains between selectboxes `Version 1.1`

A customer have some options which are related and contains constrains.
Say: You can only combine the car `vw` with one color `green` .
This is a simple implementation of such rules, using only `jQuery` .
Version 1.1: Small changes after 1st live implementation.

Car

> You can actually have more elements bound to a `data-type` !

Color
Color (single line)

> The model only needs to define the constrains seen from one of the options:
> I only "tell" which colors exists for which car. Code will "turn constrains around" and generate the "color to car" constrains.

> Two `data-attributes` on the `select` element are used to enforce constrains:
> `data-type` : The type of constrain (like car )
> `data-bound` : Which data-type is it bound to? (like color )
