My code will show that I'm very much a beginner. For the right side I'm trying to get the the filter to show and hide panels based on their value. I'm stuck and not sure where to go from where I am.

*side note any suggested reading materials/tutorials would be amazing ( obviously aside from the API/Vimeo page)
