is there a specific requirement for a custom plugin? I'm asking because in general those interactions are done on the server side. On the client side we store only few information from the database, unless you are talking about an offline feature.
You can anyway start to interact with the metadata and then do a search (or predefined query) to get what you need?
yes, it is a requirement to dynamically display a combination of the feature related attributes as labeling.
I also thought that this information is not available on the clientside by default. Could it be a solution if the feature was configured as an offline feature? What are the downsides?
Unfortunately I can not access the examples because I am blocked on BitBucket.
offline features are stored on a local H2 database. The downsides may be the footprint of the db, depending on how big is your feature (there is no tiling for such a feature).
