I have an angularUi modal window wrapped in a directive:

html:

<!doctype html>
<html ng-app="plunker">
  <head>
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.8/angular.js"></script>
    <script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.10.0.js"></script>
    <script src="main.js"></script>
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">
  </head>
  <body>
    <div my-modal="{ data: 'test2'}">test2</div>

  </body>
</html>

javascript:

angular.module('plunker', ['ui.bootstrap', 'myModal']);

angular.module("myModal", []).directive("myModal", function ($modal) {
    "use strict";
    return {
      template: '<div ng-click="clickMe(rowData)" ng-transclude></div>',
      replace: true,
      transclude: true,
      scope: {
        rowData: '&myModal' 
      },
      link: function (scope, element, attrs) {
        scope.clickMe = function () {
            $modal.open({
            template: "<div>Created By:" + scope.rowData().data + "</div>"
                        + "<div class=\"modal-footer\">"
                        + "<button class=\"btn btn-primary\" ng-click=\"ok()\">OK</button>"
                        + "<button class=\"btn btn-warning\" ng-click=\"cancel()\">Cancel</button>"
                        + "</div>",
            controller: function ($scope, $modalInstance) {
                $scope.ok = function () {
                    $modalInstance.close({ test: "test"});
                };

                $scope.cancel = function () {
                    $modalInstance.dismiss('cancel');
                };
            }
        });
        }
      }
    };
});

I want to make the modal draggable and resizable. I searched through the internet and was able to find the following solution for implementing draggable:

http://plnkr.co/edit/jHS4SJ?p=preview

This is the important part:

app.directive('dragable', function(){   
  return {
    restrict: 'A',
    link : function(scope,elem,attr){
      $(elem).draggable();
    }
  }  
});

but was not able to make it work with my example. Can someone help me with this? I wonder is it possible to use jqueryui modal wrapped in a directive (instead of bootstrap) ? I am not very good at javascript and will be very greatefull for any working example with both options. Thanks

EDIT:

I added jqueryui reference and managed to make the modal draggable by adding this line:

 $(".modal-dialog").draggable();

The problem is that I am not sure when to add this line. In the moment I have added this in the cancel method (just to make it work):

$scope.cancel = function () { $(".modal-dialog").draggable(); };

So when the modal is opened I need to call cancel and only then the modal is draggable. If I call it earlier the .modal-dialog does not yer exist. Suggestions?

I am missing something little, can someome provide working example ?

You would need to import jquery into your code, as $() is recognized by jQuery rather than angularjs – SoluableNonagon

I've created a native directive to make the modal draggable. You only need AngularJs and jQuery. The Directive uses the "modal-dialog" class from Ui-Bootstrap modal and you can only move the modal in the header.

.directive('modalDialog', function(){
  return {
    restrict: 'AC',
    link: function($scope, element) {
        var draggableStr = "draggableModal";
        var header = $(".modal-header", element);

        header.on('mousedown', (mouseDownEvent) => {
          var modalDialog = element;
          var offset = header.offset();

          modalDialog.addClass(draggableStr).parents().on('mousemove', (mouseMoveEvent) => {
                $("." + draggableStr, modalDialog.parents()).offset({
                    top: mouseMoveEvent.pageY - (mouseDownEvent.pageY - offset.top),
                    left: mouseMoveEvent.pageX - (mouseDownEvent.pageX - offset.left)
                });
            }).on('mouseup', () => {
                 modalDialog.removeClass(draggableStr);
            });
        });    
     }
  }  
});

If you don't want to modify built-in templates you can write a directive that targets modalWindow:

.directive('modalWindow', function(){
    return {
      restrict: 'EA',
      link: function(scope, element) {
        element.draggable();
      }
    }  
  });

Please note that you will have to load both jQuery and jQuery UI before AngularJS scripts.

NOTE: Also keep in mind that newer versions of Angular UI bootstrap have been prefixed with "uib" so "modalWindow" becomes "uibModalWindow" with thanks to @valepu

I combined the two above answers and made my modal dragable.

.directive('modalWindow', function(){
  return {
    restrict: 'EA',
    link: function(scope, element) {
      $(".modal-dialog").draggable();
    }
  }  
});

an Angular UI modal with a draggable title bar

NOTE: have to load both jQuery and jQuery UI before AngularJS scripts.

angular.module('xxApp')
    .directive('uibModalWindow', function () {
        return {
            restrict: 'EA',
            link: function (scope, element) {
                $('.modal-content').draggable({handle: ".modal-header"});
            }
        }
    });

Thank you for your examples. I little bit polished your code and this is my final result. to my solution it works perfectly :-)

HTML:

<div class="draggableModal ui-widget-content">

   <div class="modal-header">
     ...    
   </div>
</div>

angular.module('posProductsManager').directive('modalDialog', function () {
    var definition = {
        restrict: 'AC',
        link: function ($scope, element) {
            var draggableStr = "draggableModal";
            var header = $(".modal-header", element);
            var modalDialog = element;

            var clickPosition = null;
            var clickOffset = null;

            header[0].addEventListener('mousedown', function (position) {

                clickPosition = position;
                clickOffset = position;

                window.addEventListener('mouseup', mouseUpEvent);
                window.addEventListener('mousemove', mouseMoveEvent);
            });

            function mouseUpEvent() {
                clickPosition = null;
                window.removeEventListener('mouseup', mouseUpEvent);
                window.removeEventListener('mousemove', mouseMoveEvent);
            }

            function mouseMoveEvent(position) {

                var offset = modalDialog.parents().offset();

                $("." + draggableStr, modalDialog.parents()).offset({
                    left: clickPosition.pageX + (position.pageX - clickPosition.pageX) - clickOffset.offsetX,
                    top: clickPosition.pageY + (position.pageY - clickPosition.pageY) - clickOffset.offsetY,
                });

                clickPosition = position;
            }


        }
    };

    return definition;
});

Try using 

$(elem).closest('div.modal-dialog').draggable();

in link function
