I have an accordion that displays dynamic content. My application does not include ngAnimate, as the client does not need animations. However, I see a problem when dynamic content is hidden when ngAnimate is not enabled. When it is added back, the content displays a penalty. The scenario is that you are expanding an element of the accordion. From there, you can perform an action that will display dynamic content under the action inside the body of the accordion. The content will be disabled as soon as it passes through the height of the body of the accordion. Coagulation and expansion of the element of the accordion will lead to a recount of the body, and everything will be displayed correctly. I demonstrated the Plunker problem.
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.

If I don't understand the Angular-UI Boostrap documentation, you only need ngAnimate if you want animation.
Has anyone come across this before and found a solution? Are there any additional parameters that need to be set when the animation should be turned off? I noticed that transitions are still present even when ngAnimate is not enabled.
