Each topic has the ability to filter, for example in

https://blog.adobe.com/en/topics/news

There is a filter that looks like this

@heidichen18 , would need to work with Dominik to find out which filters will be needed, but in any case we can already start working on the functionality... most of it is there, but commented out at the moment.

Decision: filters will require a re-architecture to make it worth while for this project. For blog.adobe.com, the filters only apply for 'news' and there are only filters for Products and Industries. these hard coded values both don't make sense for us, nor are they flexible enough to give us value.

Ideally we will re-implement filters so that the author may choose which filters they want on each topic.
