I have a recyclerview which has orders. On clicking order, i need to display the products below the order. So i have used nested recyclerview (vertical-vertical). Sample UI : link
The first order item in recyclerview onclicking show lists the products list below. For the rest of the orders, on cliking order item doesnt display the product list below. The order item expands by ~10 dp with white blank space.
I know nesting recylerview with same orientation is very bad. Is there any other approach shall i use ? or continue with the same nested recyclerview.
