Hi,
I basically want to add a single component onto a page optionally, dependent
on other data/state in a page.

So far I have done this by using a ListView, and passing an empty List into
it if the component is not to be displayed.
However, I feel this is a bit heavy handed, is there any other way of
achieving the same result?

(I find ListViews to be brilliant when actually iterating through things,
but for just a single optional component it feels like overkill).
