Angular Bootstrap UI accordion not working as expected

I am using accordion component of Angular Bootstrap UI. The first accordion is expanded by default. When user add new accordion then first accordion should collapse and newly added accordion should be expand. When user clicks any accordion then it should be expanded and collapse rest of the accordions. User can add more than one accordion.

How can I achieve this?

I'm newbie to angular and Angular Bootstrap UI.

What I have done so far

Ctrl.js

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

  $scope.groups = [{
    title: 'Dynamic Group Header - 1',
    content: 'Dynamic Group Body - 1'
  }, {
    title: 'Dynamic Group Header - 2',
    content: 'Dynamic Group Body - 2'
  },  {
    title: 'Dynamic Group Header - 3',
    content: 'Dynamic Group Body - 3'
  }];


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


  // work permit form
  $scope.transforms = [{
    name: "transform",
    id: 1,
    wpformfields: [{
      employee: '',
      admount: ''
    }]
  }];

  $scope.addtransactionForm = function(transform) {
    $scope.currentnum = transform.wpformfields.length;
    //alert("hello");

    transform.wpformfields.push({
      employee: '',
      amount: ''
    });
  };

});

Solution

There is modified version which should satisfy your needs. Basically, you need to add isOpen and isDisabled property for each accordion then set isOpen to true for new accordion, others will be closed automatically.
