A 2-tier json, is used in the project. Now there is a search function. Searching Filter according to the username field in the second-tier json is a search function. If there is matching data in the second layer, it will show the first layer and the second layer data. If there is no matching data in the second layer, it will not be shown in the first layer. I want to use 2-tier filter to directly Filter out, but some can not turn around, ask for advice
the following is a screenshot of the data structure and code
