The query widget in WebApp Builder can show results with the symbology from the service. But it won't use it for the Results list. So I must use a different symbol. Because otherwise users would see the School in the Results list and it wouldn't match what is on the map.
Now, you can use a Custom symbol. But I don't want to have to download all the symbols from my map service, reload them, and also what if they change, and so forth. I propose adding the option to 'use symbol from service' to the "Icon" option as below.
