What's a good way to control an angular-ui accordion programmatically?

Question

I am using the accordion directive from http://angular-ui.github.com/bootstrap/ and I need to have more control over when the accordions open and close.

To be more preci

Answer 1

There is the is-open attribute on the accordion-group which points to a bindable expression. By using this expression you can control accordion items programatically, ex.:

<div ng-controller="AccordionDemoCtrl">
  <accordion>
    <accordion-group ng-repeat="group in groups" heading="{{group.title}}" is-open="group.open">
      {{group.content}}
    </accordion-group>    
  </accordion>
  <button class="btn" ng-click="groups[0].open = !groups[0].open">Toggle first open</button>
  <button class="btn" ng-click="groups[1].open = !groups[1].open">Toggle second open</button>
</div>

For whoever the solution by @pkozlowski.opensource is not working (me for example) you could just force the component to accept the CSS that will close it (without transition that is).

The Theory: The angular directive gets expanded into standard HTML, div elements mainly, where the CSS styles give it the appearance of the accordion. The div with class .panel-collapse is the body of the accordion-group element. You can swap its second class from .in to .collapse along with a few other changes as seen below.

The Code:

$scope.toggleOpen = function(project) {

        var id = '<The ID of the accordion-group you want to close>';
        var elements = angular.element($document[0].querySelector('#'+id));
        var children = elements.children();

        for(var i = 0; i < children.length; i++) {

            var child = angular.element(children[i]);

            if(child.hasClass('panel-collapse')) {
                if(child.hasClass('in')) { // it is open
                    child.removeClass('in');
                    child.addClass('collapse');
                    child.css('height', '0px');
                } else { // it is closed
                    child.addClass('in');
                    child.removeClass('collapse');
                    child.css('height', 'auto');
                }

            }
        }
    };

As we are talking about Angular, it is very possible that you are generating the accordion through an ng-repeat tag. In this case you can also generate the id's for the elements like:

<accordion-group ng-repeat="user in users"
                 is-disabled="user.projects.length == 0"
                 id="USER{{user._id}}">

Given a Mongoose model User, notice that the id I am giving is not user._id but has 'USER' appended in front. This is because Mongoose might generate id's that start numerically and querySelector does not like that ;-) go figure!
