Multiple Foldable elements on the same page does not work

It would be nice to have a property for the new Foldable Component, where you can do like:
TRUE as closed,
If you want the Foldable to start off closed.

Then also if we can add an icon at the front of the foldable would be nice

Also a little extra, when using the Foldable Component under some other Component, the space between those 2 components is very tiny. It would be nice if there was a bit more space added between that. (This is especially noticable when the foldeable is under a title component)

I also just found out that when you have more "Foldables" on 1 page, opening or closing a single one, opens and closes ALL of them. I think they are connected somehow...
