You should have no problem with that. 

With pure 0.1 and 0.2.* I wrote a small jQuery function for example and it's working perfectly (you can find it [here](https://github.com/mseri/rails-purecss/blob/master/app/assets/javascripts/purecss-dropdown.js), for the usage just go back and read the README of that repo)

When I have some time I check if it works with this code and eventually update it but I bet it will be pretty straightforward.
