Question

My jstree function is here.
I have set \'select_limit\' : 3, but is not working. when I run, I am able to select more than 3 nodes, but I need to select no

Answer 1

select_limit doens't handle checkbox you must roll your own before.jstree method.

j1.bind("before.jstree", function (e, data) {
    if (data.func === "check_node") {
        if (j1.jstree('get_checked').length >= 1) {
            e.preventDefault();
            return false;                
        }
    }
});

Note that this code if for example only, and doesn't handle child nodes

There is another option missing, probably need to add the ui module, try this:

j1("#utree_activity").jstree({ 
"plugins" : ["html_data","ui"],

 //the rest of your code
});
