Dynamic content hidden in Angular Bootstrap accordion

Question

I have an accordion that renders dynamic content. My app does not include ngAnimate as animations are not wanted by the client. However, I am seeing an issue where dynamic content is hidden when ngAnimate is not included. When it is added back, the content renders fine. The scenario is that you expand an accordion element. From there, you can execute an action that will render dynamic content underneath the action within the accordion body. The content will be cut off once it goes past the height of the accordion body. Collapsing and expanding the accordion element will force a recalculation of the body and everything will be displayed correctly. I've created a Plunker to demonstrate the issue.

Java Script code:

    angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('AccordionDemoCtrl', function ($scope) {
  $scope.oneAtATime = true;
  $scope.blah = ['blah'];
  $scope.view = false;


  $scope.status = {
    isFirstOpen: true,
    isFirstDisabled: false
  };
});

angular.module('ui.bootstrap.demo').directive('mydir',['$compile',function($compile){
  return{
    link:function(scope, element, attrs){
      scope.changeMe = function(){
    scope.blah.push('Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed tortor mi, molestie sit amet malesuada quis, mollis in mi.

  };
      var template = '<button type="button" class="btn btn-default btn-sm" ng-click="changeMe()">Add content below</button><div ng-repeat="stuff in blah track by $index"><div ng-if="stuff.length > 5">{{stuff}}</div></div>';
      element.empty();
      element.html(template);
      $compile(element.contents())(scope);
    },

HTML markup:

  <body>

<div ng-controller="AccordionDemoCtrl">
  <script type="text/ng-template" id="group-template.html">
    <div class="panel {{panelClass || 'panel-default'}}">
      <div class="panel-heading">
        <h4 class="panel-title" style="color:#fa39c3">
          <a href tabindex="0" class="accordion-toggle" ng-click="toggleOpen()" uib-accordion-transclude="heading"><span
            ng-class="{'text-muted': isDisabled}">{{heading}}</span></a>
        </h4>
      </div>
      <div class="panel-collapse collapse" uib-collapse="!isOpen">
        <div class="panel-body" style="text-align: right" ng-transclude></div>
      </div>
    </div>
  </script>
  <p>This demonstrates a hidden content issue when ng-animate is not present.</p>
  <p>Click "Add content below".  It will be mostly hidden.  Then collapse and expand Header 1.  The body will be recalculated and everything will be visible.</p>

  <uib-accordion close-others="false">
    <uib-accordion-group ng-init="status.open=true" is-open="status.open">
      <uib-accordion-heading>
        Header 1 - My dynamic content will disappear. <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>
      </uib-accordion-heading>
      <div><mydir></mydir></div>
    </uib-accordion-group>
    <uib-accordion-group is-open="status.isFirstOpen">
      <uib-accordion-heading>
        Header 2 <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.isFirstOpen, 'glyphicon-chevron-right': !status.isFirstOpen}"></i>
      </uib-accordion-heading>
      This content is straight in the template.
    </uib-accordion-group>


  </uib-accordion>
</div>
  </body>
</html>

Unless I am misunderstanding the Angular-UI Boostrap documentation, you only need to ngAnimate if you want animations.

Has anyone come across this before and found a solution? Is there an additional options that need to be set when animations are to be disabled? I noticed that transitions are still present even when ngAnimate is not included.

Answer 1

It's seems that in ui.bootstrap after 0.14.0 there is something that has broken this behavior but I couldn't find it in the source code yet.

If you try your code with version 0.13.4 it is working as expected. Please have a look at the updated plunkr.

Issue is already added at github. Please have a look here.
