How to query multiple layers by user-selected boundary in dashboard theme?

[SilviaFang]

I have seen this example within NYC Hazard Environment Story Map, and it is exactly what I want to do but I don't know how(see screenshots below): User can select a region and everything in the dashboard change accordingly, both map and infographics.

Q1. Is this NYC dashboard built on a single land use layer or land use plus a borough boundary layer?

Q2. I have more layers on my map (points and lines) that I want to query by a boundary layer, is it feasible?

Q3. What widget should I use to realize this function? I tried Filter, Group Filter, and Query, none works for me. They can only query within one layer, whereas I want the boundary layer to grab everything within from other layers, show them on the dashboard, and switch when user change selection.

Thank you very much!

Under the current Query Widget, I'll have to query twice which will create two new layers. First, query out one boundary shape (as a result layer) from my boundary layer, then add another query just to return features within that result boundary layer.

I need these functions in one widget, with one click of the target boundary name, and everything in the dashboard changes accordingly.
