Usage

Example Template

<md-expansion-panel md-component-id="panelOne">

  <md-expansion-panel-collapsed>
    <div class="md-title">Title</div>
    <div class="md-summary">Summary</div>
    <md-expansion-panel-icon></md-expansion-panel-icon>
  </md-expansion-panel-collapsed>


  <md-expansion-panel-expanded>

    <md-expansion-panel-header>
      <div class="md-title">Expanded Title</div>
      <div class="md-summary">Expanded Summary</div>
      <md-expansion-panel-icon></md-expansion-panel-icon>
    </md-expansion-panel-header>

    <md-expansion-panel-content>
      <h4>Content</h4>
      <p>Put content in here</p>
    </md-expansion-panel-content>

    <md-expansion-panel-footer>
      <div flex></div>
      <md-button class="md-warn" ng-click="$panel.collapse()">Collapse</md-button>
    </md-expansion-panel-footer>

  </md-expansion-panel-expanded>

</md-expansion-panel>

angular.module('app').controller('ctrl', function ($mdExpansionPanel) {
  // async
  $mdExpansionPanel().waitFor('panelOne').then(function (instance) {
    instance.expand();
    instance.collapse({animation: false});
    instance.remove();
    instance.isOpen();
  });

  // sync
  $mdExpansionPanel('panelOne').expand();
});

Example Group

<md-expansion-panel-group md-component-id="panelGroup" multiple>
  <md-expansion-panel md-component-id="panelOne">
    <md-expansion-panel-collapsed></md-expansion-panel-collapsed>
    <md-expansion-panel-expanded>
      <md-expansion-panel-header></md-expansion-panel-header>

angular.module('app').controller('ctrl', function ($mdExpansionPanelGroup) {
  // async
  $mdExpansionPanelGroup().waitFor('panelGroup').then(function (instance) {
    instance.remove('panelOne');
    instance.remove('panelTwo', {animation: false});
  });

  // sync
  $mdExpansionPanelGroup('panelOne').removeAll({animation: false});
});

Example Register Panels to group

<md-expansion-panel-group md-component-id="panelGroup" multiple>
</md-expansion-panel-group>

angular.module('app').controller('ctrl', function ($scope, $mdExpansionPanelGroup) {

  $mdExpansionPanelGroup().waitFor('panelGroup').then(function (instance) {
    instance.register('panelOne', {
      templateUrl: 'templateOne.html',
      controller: 'TemplateOneController',
      controllerAs: 'vm'
    });

    instance.register('panelTwo', {
      templateUrl: 'templateTwo.html',
      controller: 'TemplateTwoController',
      controllerAs: 'vm'
    });
  });


  $scope.addPanelOne = function () {
    $mdExpansionPanelGroup('panelGroup').add('panelOne', {localParam: 'some data'});
  };

  $scope.addPanelTwo = function () {
    $mdExpansionPanelGroup('panelGroup').add('panelTwo');
  };

  $scope.removePanelOne = function () {
    $mdExpansionPanelGroup('panelGroup').remove('panelOne');
  };

  $scope.removeAll = function () {
    $mdExpansionPanelGroup('panelGroup').removeAll({animation: false});
  };
});

mdExpansionPanelGroup

mdExpansionPanelGroup is a container to manage multiple panels

<md-expansion-panel-group
  [md-component-id=""]
  [auto-expand=""]
  [multiple=""]>
...
</md-expansion-panel-group>

md-component-id	string=	add an id if you want to acces the panel via the $mdExpansionPanelGroup service
auto-expand	string=	panels expand when added to
multiple	string=	allows for more than one panel to be expanded at a time

mdExpansionPanel

mdExpansionPanel is the main container for panels

<md-expansion-panel
  [md-component-id=""]>
...
</md-expansion-panel>

Param	Type	Details
md-component-id	string=	add an id if you want to acces the panel via the $mdExpansionPanel service

mdExpansionPanelCollapsed

mdExpansionPanelCollapsed is used to contain content when the panel is collapsed

<md-expansion-panel-collapsed>
...
</md-expansion-panel-collapsed>

mdExpansionPanelExpanded

mdExpansionPanelExpanded is used to contain content when the panel is expanded
