What's the best way to add a header to an

AdapterList

? Can it be nested in a

VerticalScroller

?

Treat it as a list item. No, it cannot be nested in a `VerticalScroller`; the same rules from RecyclerView apply to AdapterList, but we're looking to make the API easier to do these kinds of things with. There are some early design experiments with an adapter DSL that allows for assembling trees of different data sources, such as headers.
