Accordion手风琴控件使用uib-accordion和uib-accordion-group指令。

<script>

        angular.module('myApp', ['ui.bootstrap']).controller('AccordionDemoCtrl', function ($scope) {

            $scope.oneAtATime = true;

            $scope.status = {

                isFirstOpen: true,

                isFirstDisabled: false

            };

        });

</script>

<uib-accordion close-others="oneAtATime">

            <uib-accordion-group heading="标题" is-open="status.isFirstOpen" is-disabled="status.isFirstDisabled">

                内容...

            </uib-accordion-group>

</uib-accordion>

效果为：

uib-accordion的属性:

属性名称	默认值	说明
close-others	true	展开一个面板时是否关闭其他面板
template-url	template/accordion/accordion.html	在ui-bootstrap-tpls-1.3.2.js文件中使用的模板名称

uib-accordion-group的属性:

属性名称	默认值	说明
heading	none	面板头部的标题
is-disabled	false	面板是否禁用
is-open	false	面板是否展开
panel-class	panel-default	可以使用Bootstrap的样式,如panel-primary, panel-success, panel-info,panel-warning,panel-danger等。必须为字符串。
template-url	uib/template/accordion/accordion-group.html	在ui-bootstrap-tpls-1.3.2.js文件中使用的模板名称

上例中的uib-accordion-group标题和内容都是直接写在视图中的，除此之外，uib-accordion-group还有其他几种使用方式：

1. 配合ng-repeat生成面板

$scope.groups = [

              {

                  title: '第一个面板',

                  content: '第一个面板的内容'

              },

              {

                  title: '第二个面板',

                  content: '第二个面板的内容'

              }

            ];

<uib-accordion-group heading="{{group.title}}" ng-repeat="group in groups">

                {{group.content}}

</uib-accordion-group>

效果为：

2. 面板中可以包含动态生成的内容

$scope.items = ['Item 1', 'Item 2', 'Item 3'];

$scope.addItem = function () {

      var newItemNo = $scope.items.length + 1;

      $scope.items.push('Item ' + newItemNo);

 };

<uib-accordion-group heading="动态内容">

                <button type="button" class="btn btn-default btn-sm" ng-click="addItem()">Add Item</button>

                <div ng-repeat="item in items">{{item}}</div>

</uib-accordion-group>

效果为：

点击Add Item按钮后，面板的内容增加了，面板的大小也会变化，适应新的内容。

3. 使用自定义模板

uib-accordion-group默认的模板是uib/template/accordion/accordion-group.html，模板内容包含在ui-bootstrap-tpls-1.3.2.js文件中，可以参考原生的模板内容写一个自定义模板，然后用template-url来引用。

例：

 <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>

 <uib-accordion-group heading="Custom template" template-url="group-template.html">

 Hello

 </uib-accordion-group>

4. 使用自定义的面板标题

如果面板的标题是简单的文本，使用heading属性就足够了。如果是复杂的内容，比如有图标，那么可以使用uib-accordion-heading

<uib-accordion-group is-open="status.open">

     <uib-accordion-heading>

         自定义的面板标题 <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>

     </uib-accordion-heading>

     内容...

</uib-accordion-group>

效果为：

在实际使用中，如果想在点击每个面板标题时就展开控件，而不是点击文字才展开，那么加入这个样式：

.accordion-toggle { display: block; }

如果想在面板标题中加入可点击的元素（按钮，复选框等），并且点击这些元素时不展开控件，那么要在这些元素上阻止事件冒泡：

ng-click="$event.stopPropagation()"

最后，贴上完整的代码：

 <!DOCTYPE html>

         angular.module('myApp', ['ui.bootstrap']).controller('AccordionDemoCtrl', function ($scope) {

             $scope.oneAtATime = true;

             $scope.groups = [

               {

                   title: '第一个面板',

                   content: '第一个面板的内容'

               },

               {

                   title: '第二个面板',

                   content: '第二个面板的内容'

             ];

             $scope.items = ['Item 1', 'Item 2', 'Item 3'];

             $scope.addItem = function () {

                 var newItemNo = $scope.items.length + 1;

                 $scope.items.push('Item ' + newItemNo);

             };

             $scope.status = {

                 isFirstOpen: true,

                 isFirstDisabled: false

             };

         });
