I use this directiv : http://marceljuenemann.github.io/angular-drag-and-drop-lists/demo/#/types
I have problem to with moving cards, when i move cards higher is ok, if the cards give less the problem starts.
i did this feature :
if ($scope.movingItem.indeksList == index) { console.log('qrwa') $scope.lists[$scope.movingItem.indeksList].cards.splice($scope.movingItem.IndexCard +1, 1); $scope.lists[index].cards = external[index].cards; } else { console.log('qrwa2') $scope.lists[$scope.movingItem.indeksList].cards.splice($scope.movingItem.IndexCard, 1); $scope.lists[index].cards = external[index].cards; } If I do the movement in the same list and i move card higher is ok then must be perform:
$scope.lists[$scope.movingItem.indeksList].cards.splice($scope.movingItem.IndexCard +1, 1); When from up to down must be perform :
$scope.lists[$scope.movingItem.indeksList].cards.splice($scope.movingItem.IndexCard, 1); And here is problem I cant get $index on which place I drop card to make If that I move card lower make this perform, If higer make this perform...

This code works:
$scope.dropCallback = function (index, item, external) { $scope.lists[$scope.movingItem.indeksList].cards.splice($scope.movingItem.IndexCard, 1); $scope.lists[index].cards = external[index].cards; console.log($scope.lists[index].cards) return item; }; The watcher is not neccesary in this case, because you are getting informed of changes by the dropCallback function itself.
Your job is simply to remove the item at the index, like you did. Regardless of the moving direction.

Not sure why you need to use dropCallback just to move items around in the list. You can use dnd-moved="item.cards.splice($index, 1)" as shown in the demo.
Check out update version of your code:
angular.module("app", ["dndLists"]).controller("c1", function($scope){ $scope.title ="drag and drop"; $scope.lists = [ { id: 2, name: "list2", cards: [ { name: "card1"}, { name: "card2"}, { name: "card3"}, { name: "card4"}, { name: "card5"} ] }, { id: 3, name: "list3", cards: [ { name: "card1"}, { name: "card2"}, { name: "card3"}, { name: "card4"}, { name: "card5"} ] } ]; $scope.logEvent = function (indeksList, IndexCard) { $scope.movingItem = { indeksList: indeksList, IndexCard: IndexCard } }; $scope.dropCallback = function (index, item, external) { return item; }; })/* Styles go here */ .tilt { transform: rotate(3deg); -moz-transform: rotate(3deg); -webkit-transform: rotate(3deg); } .column { width: 170px; float: left; padding-bottom: 100px; } .portlet { margin: 0 1em 1em 0; padding: 0.3em; } .portlet-header { padding: 0.2em 0.3em; margin-bottom: 0.5em; position: relative; } .portlet-toggle { position: absolute; top: 50%; right: 0; margin-top: -8px; } .portlet-content { padding: 0.4em; } .portlet-placeholder { border: 1px dotted black; margin: 0 1em 1em 0; height: 50px; } /* <BEGIN> For OS X */ *:focus { outline: none; } html { -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } /* <END> For OS X */ body { font-family: 'Open Sans', sans-serif; background-color: #0375AB; } #wrapper, #topbar-inner { width: 95%; margin: 0 auto; } #topbar { background-color: #036492; } #topbar-inner { height: 42px; position: relative; } #topbar #nav { float: left; width: 25%; background: yellow; } #topbar #logo { width: 100%; padding-top: 8px; text-align: center; } #topbar #login { position: absolute; right: 0px; bottom: 10px; } #topbar #logo h1 { margin: 0; display: inline; font-size: 24px; font-family: "Ubuntu", sans-serif; color: rgba(255, 255, 255, 0.3); } #topbar #logo h1:hover { color: rgba(255, 255, 255, 0.8); cursor: pointer; } #wrapper { margin-top: 30px; } #tasks { width: 260px; padding: 7px; background-color: #E2E4E6; border-radius: 3px; } #tasks h3 { padding: 0; margin: 0px 0px 5px 0px; font-weight: 400; font-size: 14px; } #tasks ul { list-style-type: none; margin: 0; padding: 0; } #tasks li { padding: 5px 8px; margin-bottom: 4px; background-color: #fff; border-bottom: 1px #CCCCCC solid; border-radius: 3px; font-weight: 300; } #tasks li i { float: right; margin-top: 5px; } #tasks li i:hover { cursor: pointer; } #tasks li i.fa-trash-o { color: #888; font-size: 14px; } #tasks input[type=text] { margin: 0; width: 244px; padding: 5px 8px; border-width: 0; border-radius: 3px; box-shadow: none; } .btn-login { color: #fff; background-color: #448DAF; text-decoration: none; border-radius: 3px; padding: 5px 10px; }<script data-require="angular.js@1.6.5" data-semver="1.6.5" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.5/angular.min.js"></script> <script data-require="angular-drag-and-drop-lists@1.2.0" data-semver="1.2.0" src="https://marceljuenemann.github.io/angular-drag-and-drop-lists/angular-drag-and-drop-lists.js"></script> <body ng-app="app"> <div ng-controller="c1"> <ul style="list-style-type: none;"> <li ng-repeat="item in lists"> <div style="float: left; margin-left: 5px;"> <div id="tasks"> {{item.name}} <ul dnd-list="item.cards" dnd-drop="dropCallback($index, item, lists)"> <li ng-repeat="card in item.cards" dnd-draggable="card" dnd-dragstart="logEvent($parent.$index, $index)" dnd-moved="item.cards.splice($index, 1)" dnd-selected="models.selected = item" ng-class="{'selected': models.selected === item}" dnd-effect-allowed="move"> {{card.name}} </li> </ul> <form ng-submit="addTask(item._id, newTask, $index)"> <input type="text" ng-model="newTask" placeholder="add a new task" required /> </form> </div> </div> </li> </ul> </div> </body>You can find Plunker project here.
