hello everyone. Im looking for help deciding what kind of structure to use for a design made by a designer here... basically I have a list of items, and each of those can expand and have another list of items, of which some can expand again.

I explored expandable listview, but im not sure what structure I should use, maybe just a recycler view and somehow handle the expand/collapsing myself? I had a hard time getting the expandable list view to work and I believe it only works for a single level.
```          Object1:
               1.1
               1.2:
                    1.1.1
          Object2:
               2.1
               2.2
               2.3```
