Togglebox performance improvements

Do not render children if togglebox was never opened.

This works in general, but not if the toggle box includes a file input, I have found these needs to be rendered still to contain the data uploaded.
Should we have a prop maybe that forces to render children when closed?

What's the issue with a file input? Once children mount - they will remain mounted even if togglebox is later collapsed.
