Hello Alexander,

Before I answer your question, I want to notice one thing which you should
know for both questions. The renderer are not meant to be full blown widgets
which can be used in every scenario. They are more base classes or examples
on how to write form renderer. But now to your questions:

You can subclass the renderer and access the layout via _getLayout in your
subclass constructor. In all three renderer, a grid layout is used so you
can take a look at the API of the grid layout to see what you can do.

Same is true for this task. Subclass the renderer you use and the layout to
configure your desired behavior.

I hope that helps.
