    Best example of Drag and Drop using AngularJS. Designed with easy steps.

    First of all define anguler application (ng-app) name, define two directives and one controller as mentioned below. Also apply some css which will improve a look and feel of html

    Just run the snippet and enjoy the coding.

    var module = angular.module('my-app', []);
    
    module.directive('draggable', function () {
      return {
        restrict: 'A',
        link: function (scope, element, attrs) {
          element[0].addEventListener('dragstart', scope.handleDragStart, false);
          element[0].addEventListener('dragend', scope.handleDragEnd, false);
        }
      }
    });
    
    module.directive('droppable', function () {
      return {
        restrict: 'A',
        link: function (scope, element, attrs) {
          element[0].addEventListener('drop', scope.handleDrop, false);
          element[0].addEventListener('dragover', scope.handleDragOver, false);
        }
      }
    });
    
    function MainController($scope)
    {
        $scope.drag_types = [
            {name: "Charan"},
            {name: "Vijay"},
            {name: "Mahesh"},
          {name: "Dhananjay"},
        ];
        $scope.items = [];
        
        $scope.handleDragStart = function(e){
            this.style.opacity = '0.4';
            e.dataTransfer.setData('text/plain', this.innerHTML);
        };
        
        $scope.handleDragEnd = function(e){
            this.style.opacity = '1.0';
        };
        
        $scope.handleDrop = function(e){
            e.preventDefault();
            e.stopPropagation();
            var dataText = e.dataTransfer.getData('text/plain');
            $scope.$apply(function() {
                $scope.items.push(dataText);
            });
            console.log($scope.items);
        };
        
        $scope.handleDragOver = function (e) {
            e.preventDefault(); // Necessary. Allows us to drop.
            e.dataTransfer.dropEffect = 'move';  // See the section on the DataTransfer object.
            return false;
      };
               
    }
    .container {
      width: 600px;
      border: 1px solid #CCC;
      box-shadow: 0 1px 5px #CCC;
      border-radius: 5px;
      font-family: verdana;
      margin: 25px auto;
    }
    
    .container header {
      background: #f1f1f1;
      background-image: -webkit-linear-gradient( top, #f1f1f1, #CCC );
      background-image: -ms-linear-gradient( top, #f1f1f1, #CCC );
      background-image: -moz-linear-gradient( top, #f1f1f1, #CCC );
      background-image: -o-linear-gradient( top, #f1f1f1, #CCC );
      box-shadow: 0 1px 2px #888;
      padding: 10px;
    }
    
    .container h1 {
      padding: 0;
      margin: 0;
      font-size: 16px;
      font-weight: normal;
      text-shadow: 0 1px 2px white;
      color: #888;
      text-align: center;
    }
    
    .container section {
      padding: 10px 30px; 
      font-size: 12px;
      line-height: 175%;
      color: #333;
    }
