Answer 1

In you day cell, create another recycler view that hold ( vertical item ). Assume that each position have different list of data so collect data from each parent position and set to childAdapter of each position

3. Create ChildAdapter for ChildRecyclerView that holding vertical item using ChildViewHolder.
