1.just take city example , drop active reason work , take again city out of active reason still fine. again if try add city in active reason city block invisible.

with each drag perform sort operation dynamically.

$(function() { $( "#sortable1, #sortable2" ).sortable({   connectwith: ".connectedsortable",   helper: 'clone',   containment:"document",   revert:"true",   tolerance:"pointer"    });  });   $("#sortable2").sortable({   stop: function ( event, div){   data = $(this).sortable('toarray', { attribute: 'data-id' });   //here perform our ajax request  },  receive: function (event, ul) {   ul.item.remove();  }  });   //with each drag connect sort  $("#sortable1>div").draggable({    connecttosortable: "#sortable2",    helper: "clone",    revert: "invalid",    axis :"y"    });  $("#sortable2>div").draggable({ connecttosortable: "#sortable2", helper: "clone", revert: "invalid" });  //here html reference     <div id="sortable2" class="connectedsortable"> <span class="ui-sortable-handle">  active</span></div>     <div id="sortable1" class="connectedsortable">      // here have list of element want drag    </div>
