If you want open all node when tree loaded:

$("#treeview")
    // call `.jstree` with the options object
    .jstree({
        "plugins" : ["themes", "html_data","ui","crrm","sort"]
    }) 
    .bind("loaded.jstree", function (event, data) {
        // you get two params - event & data - check the core docs for a detailed description
        $(this).jstree("open_all");
    })      
});
