checkbox get disabled in ng-repeat of accordions

Question

I have build a list of accordions, each accordion represent a group of items. I have used ng-repeat to iterate through group names,each group has a checkbox which indicate if it is chosen or not.

The example works fine for single group of accordion, but the moment I am putting the accordion inside ng-repeat, the checkbox can't be selected at all.

Here is the code, the main checkbox of each group title doesn't work apparently, I am try to figure out the reason for this.

My main Question is:

1.How can I make the checkboxes of Group1 and Group2 and Group3 active,so I can select them properly, In current situation, I can't select the checkboxes at all(of Group1,Group2 and Group3).

var app = angular.module('app',[]);

app.controller('mainCTRL',function($scope){
  $('.collapse').collapse();
  $scope.title="Hello World";
  $scope.items1 = ['Group1','Group2','Group3']
})

.ui-checkbox {
  display: none;
}
.ui-checkbox + label {
  position: relative;
  padding-left: 25px;
  display: inline-block;
  font-size: 14px;
}
.ui-checkbox + label:before {
  background-color: #fff;
  /**#fff*/
  border: 1px solid #1279C6;
  padding: 9px;
  border-radius: 3px;
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  content: "";
}
.ui-checkbox:checked + label:before {
  border: 1px solid #1279C6;
  color: #99a1a7;
}
.ui-checkbox:checked + label:after {
  content: '\2714';
  font-size: 14px;
  position: absolute;
  top: 1px;
  left: 4px;
  color: #1279C6;
}

Answer 1

The problem is because your checkboxes are nested inside anchors. Simply change:

<a data-toggle="collapse" data-parent="#accordion-{{$index}}"
                       data-target="#collapseOne-{{$index}}">

To:

<div data-toggle="collapse" data-parent="#accordion-{{$index}}"
                       data-target="#collapseOne-{{$index}}">

See working example:

var app = angular.module('app',[]);

app.controller('mainCTRL',function($scope){
  $('.collapse').collapse();
  $scope.title="Hello World";
  $scope.items1 = ['Group1','Group2','Group3']
})

.ui-checkbox {
  display: none;
}
.ui-checkbox + label {
  position: relative;
  padding-left: 25px;
  display: inline-block;
  font-size: 14px;
}
.ui-checkbox + label:before {
  background-color: #fff;
  /**#fff*/
  border: 1px solid #1279C6;
  padding: 9px;
  border-radius: 3px;
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  content: "";
}
.ui-checkbox:checked + label:before {
  border: 1px solid #1279C6;
  color: #99a1a7;
}
.ui-checkbox:checked + label:after {
  content: '\2714';
  font-size: 14px;
  position: absolute;
  top: 1px;
  left: 4px;
  color: #1279C6;

Answer 2

The problem is the ids you assigned. Make the ids unique, and the checkbox starts working. Here is the fixed snippet

var app = angular.module('app',[]);

app.controller('mainCTRL',function($scope){
  $('.collapse').collapse();
  $scope.title="Hello World";
  $scope.items1 = ['Group1','Group2','Group3']
})

.ui-checkbox {
  display: none;
}
.ui-checkbox + label {
  position: relative;
  padding-left: 25px;
  display: inline-block;
  font-size: 14px;
}
.ui-checkbox + label:before {
  background-color: #fff;
  /**#fff*/
  border: 1px solid #1279C6;
  padding: 9px;
  border-radius: 3px;
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  content: "";
}
.ui-checkbox:checked + label:before {
  border: 1px solid #1279C6;
  color: #99a1a7;
}
.ui-checkbox:checked + label:after {
  content: '\2714';
  font-size: 14px;
  position: absolute;
  top: 1px;
  left: 4px;
  color: #1279C6;
}
