Methods 28

virtual bool CanChangeExpandedState(int id)

Whether an item may expand or collapse (any item may, as in Unity).

void CollapseAll()

void CollapseItem(int id, bool collapseAllChildren, bool refresh = true)

void CollapseItemByIndex(int index, bool collapseAllChildren, bool refresh = true)

bool Exists(int id)

void ExpandAll()

void ExpandItem(int id, bool expandAllChildren, bool refresh = true)

void ExpandItemByIndex(int index, bool expandAllChildren, bool refresh = true)

virtual IEnumerable<int> GetAllItemIds(IEnumerable<int>? rootIds = null)

Each root's children, then the root (as Unity's lists them; deeper items aren't).
