Angular JS - Modal not shown properly

Question

I am learning to use Modal in AngularJS and Bootstrap 4 framework. I have manage to show it, but it is not shown properly, i.e. blocking components in background and cannot be shown if animation: true. I am not sure what causing this because I have inject ngAnimate and ui.bootstrap in my app controller.

Angular and ui-bootstrap version used

• Angular v1.6.4
• UI-bootstrap v2.5.0

Below I will provide my code.

View.html

<div class="container-fluid content-container" ng-app="listEmployee">
<div class="change-password-modal-container"></div>
  <script type="text/ng-template" id="myModalContent.html">
    <div class="modal-header">
        <h3 class="modal-title" id="modal-title">I'm a modal!</h3>
    </div>
    <div class="modal-body" id="modal-body">
        <ul>
            <li ng-repeat="item in ctrl.items">
                <a href="#" ng-click="$event.preventDefault(); ctrl.selected.item = item">{{ item }}</a>
            </li>
        </ul>
        Selected: <b>{{ ctrl.selected.item }}</b>
    </div>
    <div class="modal-footer">
        <button class="btn btn-primary" type="button" ng-click="ctrl.ok()">OK</button>
        <button class="btn btn-warning" type="button" ng-click="ctrl.cancel()">Cancel</button>
    </div>
  </script>
  ... <!--other html elements -->
</div>

Below is my code in controller which is related to showing the modal

Controller.js

var ctrl = this;
    ctrl.items = ['item1', 'item2', 'item3'];
    ctrl.animationsEnabled = false;
    ctrl.open = function (size, parentSelector) {
        var parentElem = parentSelector ? 
          angular.element($document[0].querySelector('.change-password-modal-container ' + parentSelector)) : undefined;
        var modalInstance = $uibModal.open({
          animation: ctrl.animationsEnabled,
          ariaLabelledBy: 'modal-title',
          ariaDescribedBy: 'modal-body',
          templateUrl: 'myModalContent.html',
          controller: 'ModalInstanceCtrl',
          controllerAs: 'ctrl',
          size: size,
          appendTo: parentElem,
          resolve: {
            items: function () {
              return ctrl.items;
            }
          }
        });
        modalInstance.result.then(function (selectedItem) {
          ctrl.selected = selectedItem;
        }, function () {
          $log.info('Modal dismissed at: ' + new Date());
        });
  };

The z-index of my content is 1

mystyle.css

#content {
    z-index: 1;
}

Below is the screenshot when the animation:false

Below is the screenshot when the animation:true (i.e. modal is not visible, it's like the modal is behind the screen)

Any help would be appreciated.

After reading this issue in GitHub, turns out this is the problem when using Bootstrap 4. Bootstrap 4 has different class names with Bootstrap 3, in this case, it is .in in version 3 become .show in version 4.

Following as suggested by IdanCo in the thread, which I rewrite below (so it will be easier for others to read) fixed this issue.

Change the class names from ui-bootstrap-tpls-###.js as below.

             'class': 'modal-backdrop',
             'ng-style': '{\'z-index\': 1040 + (index && 1 || 0) + index*10}',
             'uib-modal-animation-class': 'fade',
             'modal-in-class': 'in'   //change this
             'modal-in-class': 'show' //to this
           });
           if (modal.backdropClass) {
             backdropDomEl.addClass(modal.backdropClass);

           'ng-style': '{\'z-index\': 1050 + $$topModalIndex*10, display: \'block\'}',

           'uib-modal-animation-class': 'fade',
           'modal-in-class': 'in'   //change this
           'modal-in-class': 'show' //to this
         }).append(content);
         if (modal.windowClass) {
           angularDomEl.addClass(modal.windowClass);

Hope this update could help someone in the future.
