Basic Example - array input

+

+ The nodes prop for the CheckboxTree is provided as an array of child nodes of the root of the tree. +

+

Basic Example - object input

+

+ The nodes prop for the CheckboxTree is provided as the root node object instead of an array of child nodes of the root of the tree. +
