Expand collapse list item using angular material

Question

Can anyone give any suggestions for adding an Expand/Collapse view shown here. I'd like to use Angular material with AngularJS only and not be dependant on Bootstrap etc however I can't find anything suitable in the AngularMaterial docs.

Thanks

One way is to use 2 consecutive md-list-item.

Here is the HTML Code.

  <md-list flex>
   <md-list-item ng-click="toggle.list1 = !toggle.list1">
    <md-icon>explore</md-icon>
    <span flex>Item List 1</span>
    <md-icon ng-show="!toggle.list1">expand_more</md-icon>
    <md-icon ng-show="toggle.list1">expand_less</md-icon>
   </md-list-item>
   <md-list-item ng-repeat="item in data" ng-show="toggle.list1">
   <span flex-offset="5">{{item}}</span>
  </md-list-item>
  <md-list-item ng-click="toggle.list2 = !toggle.list2">
   <md-icon>explore</md-icon>
   <span flex>Item List 2</span>
   <md-icon ng-show="!toggle.list2">expand_more</md-icon>
   <md-icon ng-show="toggle.list2">expand_less</md-icon>
  </md-list-item>
  <md-list-item ng-repeat="item in data" ng-show="toggle.list2">
   <span flex-offset="5">{{item}}</span>
  </md-list-item>
 </md-list>

JS Code:

angular.module('myApp',['ngMaterial'])
.controller('TempController', function($scope){
 $scope.data = [ "Item 1", "Item 2", "Item 3", "Item 4"]
 $scope.toggle = {};
});;

Here is the working Codepen.

This doesn't seem to use bootstrap.

this should be possible code to make your own accordion with material

Do you know if there's and example that uses just AngularMaterial? I'm not able to add extra libraries at this stage.

To animate the Expand/Collapse transition, you may consider using ngAnimate. It's really simple as adding a section-show-hide class to the hidden element, and this css code: .section-show-hide { transition: all linear 0.5s; max-height: 500px; } .section-show-hide.ng-hide { opacity: 0; max-height: 0; }
