multiselectable dropdown checkboxes using angular js

Question

I want to design a dropdownlist of checkboxes and make the checkboxes multi-selectable. I have used the below code,but I am unable to make multiple selections as the template refreshes each time I click on a checkbox,please suggest some ideas?

{   <ul class="status-select" class="status-select" ng-if="$index == selectedFilterIndex">
     <li ng-repeat="DataValue in filter.Data.Value">
        <input type="checkbox" ng-click="OnDropDownSelectionChanged(filter,DataValue)">
                        {{DataValue.displayText}}
     </li>
     </ul> 
}

Solution 1

You can use directive like angularjs-dropdown-multiselect, which you can find very easily on internet

Here are some example:

1. angularjs-dropdown-multiselect - Fiddle

2. multiselectDropdown - Fiddle

3. Another example of angularjs-dropdown-multiselect - Fiddle

Code Snippet:

var myApp = angular.module('exampleApp', ['angularjs-dropdown-multiselect']);

myApp.controller('appController', ['$scope',
  function($scope) {

    $scope.example13model = [];
    $scope.example13data = [{
      id: 1,
      label: "David"
    }, {
      id: 2,
      label: "Jhon"
    }, {
      id: 3,
      label: "Lisa"
    }, {
      id: 4,
      label: "Nicole"
    }, {
      id: 5,
      label: "Danny"
    }];

    $scope.example13settings = {
      smartButtonMaxItems: 3,
      smartButtonTextConverter: function(itemText, originalItem) {
        if (itemText === 'Jhon') {
          return 'Jhonny!';
        }

        return itemText;
      }
    };
  }
]);

div, h1, a {
  padding: 5px;
}

Solution 2

a simple workaround that I've found is using Angular Directives for Bootstrap using the auto-close="outsideClick" and the code should be like this:

<div class="dropdown" uib-dropdown auto-close="outsideClick" on-toggle="toggled(open)">
  <a class="btn btn-primary" uib-dropdown-toggle>Toggle</a>
  <ul class="dropdown-menu status-select" class="status-select" ng-if="$index == selectedFilterIndex" uib-dropdown-menu>
    <li ng-repeat="DataValue in filter.Data.Value">
      <div class="checkbox">
        <label>
          <input type="checkbox" ng-click="OnDropDownSelectionChanged(filter,DataValue)">
                      {{DataValue.displayText}}
        </label>
      </div>
    </li>
  </ul>
</div>

You could go for Angular Material Design Library

Select with Option Groups

Wow the number 3 is pretty awesome! Remember not to use external scripts in your real project. Somebody might inject some crazy stuff in to your external lib...(man in the middle attack)
