Dynamic Filtering based on Web Map Selection

Hi All,


I have a theoretical question about using web app builder/AGOL/API/ Whatever else is required to do this. I found an API thread from 2012 that has a similar question to what I have which is, how do you link feature classes visibility to the selection of another feature class in the web map. I imagine this would work similarly to an "Ask For Values" filter in AGOL, but the values would be dynamic and linked based in map selection. I have looked at the Query Widget and I am still unclear if it provides exactly what I am thinking about.
Example Scenario: I have a map of Census Tracts, and whenever I click on a Census tract, I want to see a conventional 3 mile buffer from its centroid that is filtered based on some unique ID in the Census tract. All the other buffer sin the feature class this buffer comes from do not appear, only the one selected by the user. Conventionally, I have solved this problem with pop ups that show a static map/infographic/image that is associated with the point of interest. I was hoping someone might have an idea or example of this type of behavior in the wild.


Thoughts or help would be great.
