Properties

canSelectMany ↔ bool?

Available on TreeViewOptions<T>, provided by the TreeViewOptions$Typings extension

no setterinherited
manageCheckboxStateManually ↔ bool?

Available on TreeViewOptions<T>, provided by the TreeViewOptions$Typings extension

By default, when the children of a tree item have already been fetched, child checkboxes are automatically managed based on the checked state of the parent tree item. If the tree item is collapsed by default (meaning that the children haven't yet been fetched) then child checkboxes will not be updated. To override this behavior and manage child and parent checkbox state in the extension, set this to true.
