All subNodes been checked when parentNode been checked

[Shuai-Meng]

I hope when check a parentNode, all its subNodes won't been checked. Or at least this can be configured, some people may just want check the parentNode only.
And the toggle feature, sometimes I just want to choose one node, rather than expand it. So I hope clicking the node name and the node 'tpl' will be different.
Thank you!
