Usage

• If you use bower, just bower install v-accordion. If not, download files from the github repo.

• Include angular.js, angular-animate.js, v-accordion.js, and v-accordion.css: ```html

  - Add `vAccordion` as a dependency to your application module:
  ```js
  angular.module('myApp', ['vAccordion']);

• Put the following markup in your template: ``html <!-- addmultiple` attribute to allow multiple sections to open at once -->

  Pane header #1
  

  Pane content #1
  

  Pane header #2
  

  Pane content #2
  

  - You can also use `v-accordion` with `ng-repeat`:
  ```html
  <v-accordion class="vAccordion--dafault">

    <v-pane ng-repeat="pane in panes" expanded="$first">
      <v-pane-header>
        {{ pane.header }}
      </v-pane-header>

      <v-pane-content>
        {{ pane.content }}
        
        <!-- accordions can be nested :) -->
        <v-accordion ng-if="pane.subpanes">
          <v-pane ng-repeat="subpane in pane.subpanes">
            <v-pane-header>
              {{ subpane.header }}
            </v-pane-header>
            <v-pane-content>
              {{ subpane.content }}
            </v-pane-content>
          </v-pane>
        </v-accordion>
      </v-pane-content>
    </v-pane>

Use these callbacks to get expanded/collapsed pane index:

<v-accordion onexpand="expandCallback(index)" oncollapse="collapseCallback(index)">

  <v-pane ng-repeat="pane in panes">
    <v-pane-header>
      {{ pane.header }}
    </v-pane-header>

    <v-pane-content>
      {{ pane.content }}
    </v-pane-content>
  </v-pane>

</v-accordion>

$scope.expandCallback = function (index) {
  console.log('expanded pane index:', index);
};

$scope.collapseCallback = function (index) {
  console.log('collapsed pane index:', index);
};

Accessibility

vAccordion manages keyboard focus and adds some common aria-* attributes. BUT you should additionally place the aria-controls and aria-labelledby as follows:

<v-accordion>

  <v-pane ng-repeat="pane in panes">
    <v-pane-header id="pane{{$index}}-header" aria-controls="pane{{$index}}-content">
      {{ pane.header }}
    </v-pane-header>

    <v-pane-content id="pane{{$index}}-content" aria-labelledby="pane{{$index}}-header">
      {{ pane.content }}
    </v-pane-content>
  </v-pane>

</v-accordion>
