Add External Stylesheets/Pens

Any URLs added here will be added as <link>s in order, and before the CSS in the editor. You can use the CSS from another Pen by using its URL and the proper URL extension.

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Add Packages

Search for and use JavaScript packages from npm here. By selecting a package, an import statement will be added to the top of the JavaScript editor for this package.


Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.

Format on Save

If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

  <div ng-controller="Ctrl">
    <div ng-repeat="week in weeks track by">

            <td>{{ }}</td>
            <td><input type="text" ng-model="day.text" ng-blur="saveWeeks()"></td>
    <div ng-if="!week._expanded" class="collapsed">
        <tr ng-repeat="day in week._days">
          <td><b>{{ }}</b></td>
          <td>{{ day.text }}</td>
      Click to edit the week entries. After reloading the page you
      get back what you typed last.
      A useful extension of this would be to be able to add new weeks. And make it infinitely prettier.
