<iron-pages>
iron-pages is used to select one of its children to show. One use is to cycle through a list of
children "pages".
Example:
<iron-pages selected="0">
<div>One</div>
<div>Two</div>
<div>Three</div>
</iron-pages>
<script>
document.addEventListener('click', function(e) {
var pages = document.querySelector('iron-pages');
pages.selectNext();
});
</script>Notable breaking changes between 1.x and 2.x (hybrid):
IronSelectableBehavior and IronMultiSelectableBehavior, which are used by iron-pages, introduce multiple breaking changes. Please see the README for those behaviors for more detail.
