Collapse default open

[itaiperi]

Hi Benji,

Wanted to suggest an improvement to the Collapse component - a defaultOpen attribute, that will set the Collapse to be open by default on mount, but will have a default value of false, to keep backward compatibility of course.
This will enable to have the collapse open at the beginning, without taking full control over opening and closing from a controlling component, which can be cumbersome.

I've had several such use-cases over the past few weeks.

What do you say? I'm willing to implement this, if you'll give it the green light.

@itaiperi that would be great, and looking back, I'm surprised we don't have this. Feel free to open a PR!

This is a great suggestion, and I'd like to propose adding a defaultOpen prop (defaulting to false) to initialize the collapse state on mount without affecting controlled usage. If no one has taken this on yet, I'd love to work on it.
