How can I build my tree with a check box or radio button in front of tree node? The style of treeview showcase can't need my demands..for example, the checkbox style tree, its checkbox is pictures not a real html checkbox element, and the single selection tree I want to use a radio button selected instead of highlight effect. I need some help, thanks advance..
