How do I prevent jsTree from rendering checkboxes on all but leaf nodes?

I have a request to only have the leaf nodes of the tree have the option of being selected.

This tree is being populated with the json_data plugin. Is there an option available either in the data or through the api to remove checkboxes or prevent them from be开发者_运维百科ing rendered?
