-Customising the tabbed interface
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Wagtail organises panels into three tabs: 'Content', 'Promote' and 'Settings'. Depending on the requirements of your site, you may wish to customise this for specific page types - for example, adding an additional tab for sidebar content. This can be done by specifying an ``edit_handler`` property on the page model. For example:
-
-.. code-block:: python
-
-    from wagtail.wagtailadmin.edit_handlers import TabbedInterface, ObjectList
-
-    class BlogPage(Page):
-        # field definitions omitted
-
-    BlogPage.content_panels = [
-        FieldPanel('title', classname="full title"),
-        FieldPanel('date'),
-        FieldPanel('body', classname="full"),
-    ]
-    BlogPage.sidebar_content_panels = [
-        SnippetChooserPanel('advert', Advert),
-        InlinePanel('related_links', label="Related links"),
-    ]
-
-    BlogPage.edit_handler = TabbedInterface([
-        ObjectList(BlogPage.content_panels, heading='Content'),
-        ObjectList(BlogPage.sidebar_content_panels, heading='Sidebar content'),
-        ObjectList(BlogPage.promote_panels, heading='Promote'),
-        ObjectList(BlogPage.settings_panels, heading='Settings', classname="settings"),
