Question

I am using the JQuery plugin jsTree, http://www.jstree.com/ I am able to expand the whole tree with the following method:

$(\"#tree\").jstree(\"open_all\");
         


        

Answer 1

Try this code to open node till nth Level

$("#myTree").jstree({options}).bind('loaded.jstree', function (e, data) {
    /** 
     * Open nodes on load (until x'th level) 
     */
    var depth = 3;
    data.inst.get_container().find('li').each(function (i) {
        if (data.inst.get_path($(this)).length <= depth) {
            data.inst.open_node($(this));
        }
    });
});
