ListView Expansion Performance Questions

NPC

I've been trying to create a section of my app that includes a list

I'd like each item to expand to reveal more information, and only allow one cell to be expanded at any one time

I'be mostly run into issues on iOS achieving this. All the solutions seem to cause massive visual errors (cells clipping into each other) and lag. I've even gone as far as to find a way to call UITableView.ReloadRows from the PCL when on iOS instead of ForceUpdateSize

Are there any suggested ways to achieve a decent level of performance on iOS?
Since the iOS Simulator tends have some weird visual issues, is it just the simulator?
