Restore drag and drope positions

Question

I use drag and drope jquery ui in my code. And the code works fine. But user should have some ability to edit data after saving. It means that I need to restore drag and drope positions when user opens the page again. I try to use trigger but I can't emulate "drop ui" How can I do it?

$( ".draggable-children-username" ).draggable({
    snap: ".draggable-in-box",
    opacity: 0.7,
    revert: 'invalid',
    helper: "clone"
});
$(".draggable-in-box").droppable({
    accept: $(".draggable-children-username"),
    hoverClass: "dropHover",
    drop: function (ev, ui) {
        $(this).trigger("DopeEvent", ui);
    }
});

$( ".draggable-in-box" ).bind("DopeEvent", function(event, ui ){
    console.log(ui);

    var me = ui.draggable.clone()
    ui.draggable.draggable("disable")
    me.appendTo(this)
    .addClass("newClass");
    me.draggable({
        accept: ".draggable-in-box",
        revert: function(valid) {
            if(!valid) {
                this.remove();
                $(".dr-children-id-"+this.attr("data-id")).draggable("enable");
            }
        }
    });
});

$( ".draggable-in-box" ).trigger("DopeEvent", $( ".dr-children-id-140" ));

Current error: Uncaught TypeError: ui.draggable.clone is not a function

A few fixes. Working example of what I think you're trying to do:

JQuery

$(".draggable-children-username").draggable({
  snap: ".draggable-in-box",
  opacity: 0.7,
  revert: 'invalid',
  helper: "clone"
});

$(".draggable-in-box").droppable({
  accept: $(".draggable-children-username"),
  hoverClass: "dropHover",
  drop: function(ev, ui) {
    $(this).trigger("DopeEvent", ui.draggable);
  }
});

$(".draggable-in-box").bind("DopeEvent", function(event, ui) {
  console.log(ui);

  var me = $(ui).clone();
  //ui.draggable.draggable("disable")
  me.appendTo(this)
    .addClass("newClass");
  me.draggable({
    accept: ".draggable-in-box",
    revert: function(valid) {
      if (!valid) {
        this.remove();
        $(".dr-children-id-" + this.attr("data-id")).draggable("enable");
      }
    }
  });
});

$(".draggable-in-box").trigger("DopeEvent", $(".dr-children-id-140"));

1. Do not assume you're being passed a draggable object or a jquery object in you DopeEvent. Use var me = $(ui).clone();
2. In your drop, you need to pass the element like so: $(this).trigger("DopeEvent", ui.draggable);

Hope that helps. You could improve your event by checking what is being passed. Something like if(typeof ui === "object"){} could work.
