How to config contextmenu for different typs of nodes in jstree?

Question

I use 'contextmenu' and 'types' plugin in jstree and want to define different contextmenu according to the 'types', like this:

$("#tree").jstree({
    "plugins" : [ "themes", "json_data", "ui", "contextmenu", "types" ],
    "themes" : {
        "url" : "css/jstree/themes/classic/style.css",
        "theme" : "classic",
        "icons" : false
    },
    "json_data" : { "data" : data },
    "types": {
        "types": {
            "leaf": { "contextmenu" : { items : contextMenu } }
        }
    }
});

but it doesn't work, it displays the same contextmenu for all nodes, no specified one as I defined for 'leaf' nodes. Is it because cannot define contextmenu in type? Then how to achieve this easily.

You have to define the context menu in the context menu plugin section. I think the best way at the moment is to define all items for all nodes and then delete items according to the node type, or even better - define a function that returns the context menu according to the node. i.e, this is how you'd usually define the contextmenu without a function:

    "contextmenu" : {
        items: {
            "some_action" : {
                "label" : "Do something",
                "action"            : function (obj) { this.do_action(obj); },
                "_disabled"         : function (obj) { 
                    // here you can decide if you want to show the item but disable it
                }
            };
            // define more items
        };
         if (data.rslt.o.attr("rel") == "no_action") {
            delete items.some_action;
        }
    return items;
}
