RecyclerView for parents and another RecyclerView for children

[AlaaZarifa]

I applied your library with json data, and it's working perfectly, but the RecyclerView right now is for a list of parents with fixed-size children, but for the json that I'm working on, there's a list for the children themselves.. so how can I accomplish that..!?

do I add recyclerview inside the layout#2 (child) within the ExpanalbeLayout widget..!? if it's gonna work, would show me how, in simple steps..!

thnx
