I am getting huge data from json which needs to be shown in Parent-Child tables as attached sample pic. I tried it using Matrix as they have put demo projects similar to my requirement but I’m not able to find out how to achieve it. I downloaded Matrix widget and able to put like a tree view but don’t know to how to do configuration for List kind of view.
Are you trying to show a list of lists?
ex. From a list of countries, when you select a country, the states related to it should be shown,
