[jQuery] Create a Treeview with a checkbox

[Michelangelo]

Hi guys

I am using this plugin (http://bassistance.de/jquery-plugins/jquery-
plugin-treeview/) to create a treeview in async mode with Country-
>Regions->Provinces but I need to use the checkbox for each item.

I have added into the code this code:
<input type='checkbox' name='geo[]'> but I suppose that there is
another clear way to do this job.


this is the code:

                        var current = $("<li/>").attr("id", this.id ||

type='checkbox' name='geo[]'> <span>" + this.text + "</span>").appendTo

                        if (this.classes) {
                                current.children("span").addClass(this.classes);
                        }
