Please update Collapse/Expand item API to make it
1) Standard: Collapse/Expand item should accept same parameters as select/deselect item methods do.
Namely: Collapse/Expand item should accept item index as a parameter.
Same as in : selectItem(item) - item (Object|number)
2) Usable from DART
Dart makes it non-trivial to use item JavaScript Object as a parameter.
Especially some dynamically generated JavaScript Object as a parameter - please don't make DART users work around it.
feature request - would it somehow be possible to fully synchronize selection and expanding, so the not selected items are collapsed and selected item/s are expanded
