Is it possible to pin parents to the top?

[jubby2000]

I have a longer parent/child list, and I thought it would make sense to pin the parent to the top on expansion, until scrolling occurs past that position, at which time it will be replaced by the next one, etc. Is this possible?

A a b c B

upon scroll would look like

A c B

Very cool idea @jubby2000, it would be possible but not currently implemented in this library. It would be a mix of something like https://github.com/bgogetap/StickyHeaders and this library. Currently we are focused on improving the expand/collapse side of things so I don't think it'll something we have time to work on just yet.
