Question

Here I have my list with 2 submenu. I don't understand why I can't do "drag and drop"
of any element of the list. I got this script in internet but I think I have done everything good.Maybe I don't see something very easy and sorry for that in advance!

La solution

You should put the following section inside the document ready:

$('ul').disableSelection().sortable({

so that it becomes:

function mkUl(){ 
    $("ul").each(function(){
        $(this).removeAttr("class");

        var ulLevel = $(this).parents('ul').length+1;
        $(this).addClass("ui-sortable no-child level_"+ulLevel);
        var childC = $(this).children("li").size(); 
        $(this).has("li").removeClass("no-child").addClass("child children-"+childC);

        $(this).children("li:first").addClass("first");
        $(this).children("li:last").addClass("last");
    }); 
}

$(document).ready(function(){
    mkUl();
    $('ul').disableSelection().sortable({
        connectWith: "ul",
        tolerance: "pointer",
        cursorAt: {
            left: 40,
            top: 20
        },
        cursor: "move",
        opacity: 0.5,
        placeholder: "highlighter",
        helper: "clone",
        revert: 200,
        start: function(e, ui) { 
            if(ui.item.parent().hasClass("children-1")){
                ui.item.parent("ul").removeClass("child").addClass("no-child");
            }
        },
        stop: function(e, ui) { 
            mkUl();
        }
    });

});

Hope this helps
