Event Categories and Filter Bubbles on Calendar Embedd

we want to guide our audience experience by providing "One-Click filters" for vrious types of events. I think they work seprate form Groups where Groups would allow for promotional grouping around Sail250 or July 4th Weekend. vs categories that can help filter to specifically show fitness classes or live music. we found great use in our winter map were we could show categories like Christmas Trees and Holiday markets at the same time.
