I have a conflict when trying to mix those plugins, i have based my script in some demos. The problem is that when i drag something inside the same list it triggers the drop event and that item is added to the end of the list, wich is correct if the item is dropped in another list, but not in the same, when i drop it in the same list i want to insert it in that position (it works if i disable the drop event)

js code:

$(document).ready(function() {
      $("#sortlist1").treeview();
      $("#sortlist1").droppable({  
        accept: ".item",  
        drop: function(ev, ui) {
            alert(ui.sender)
            $("#sortlist1").append($(ui.draggable));     
        } 
      });  
      $("#sortlist2").droppable({  
            accept: ".item",
            drop: function(ev, ui) {
                $("#sortlist2").append($(ui.draggable));  
            }  
          });
      $("#sortlist3").droppable({  
            accept: ".item",  
            drop: function(ev, ui) {
                $("#sortlist3").append($(ui.draggable));  
            }  
          });
      $('.sortlist').sortable({
          handle : '.icono',
          update : function () {
              $('input#sortlist').val($('.sortlist').sortable('serialize'));
          }
        });
    });

And html:

<ul class="sortlist treeview lista" id="sortlist1">
        <li id="listItem_1" class="expandable closed item">
            <div class="hitarea closed-hitarea expandable-hitarea lastExpandable-hitarea">

Sorted by: Reset to default 7

You cannot mix those plugins: they process the same events, and cannot cooperate together. Either rethink your UI, or use different tools.

Is it possible to do it? Yes, of course. For example, Dojo DnD allows both sorting and drag-and-drop using just one ponent: test_dnd.html (link to the debugging server).

You can do this, sort of.

Create two links in each item to use as handles.

Make the list sortable by one handle.

Make the list draggable by the other handle.

Now, when you grab one handle or the other, only one plugin will be activated, and events will be processed correctly.

If you want to move a <li> element from one list to another, you can simply use the connectWith property of sortable(). Just look in the documentation.

I had a similar conflict between Drag/Drop and Sortable JS, where sorting inside the list was triggering an unwanted drop event to the list.

I solved it by testing for data from the drag event in my drop handler. If the data was present, the drop handler treated the event as a drop event. If it was not, it treated it as a sort event.

Here's an example script for the drag event:

$('body').on('dragstart', '.drag-object', function(event) {
    const data = 'some-data;
    event.originalEvent.dataTransfer.setData('text', data);
});

And here's an example script for the drop handler:

$('body').on('drop', '.drop-target', function(event) {
    event.preventDefault();
    const test = event.originalEvent.dataTransfer.getData('text');
    if (test.includes('some-data')) {
        // Treat as drag/drop
    } else {
        // Treat as sort
    }
}
