Available panel types¶
FieldPanel(field_name, classname=None, widget=None)¶
This is the panel used for basic Django field types.
This is the name of the class property used in your model definition.
This is a string of optional CSS classes given to the panel which are used in formatting and scripted interactivity. By default, panels are formatted as inset fields.
The CSS class
fullcan be used to format the panel so it covers the full width of the Wagtail page editor.
The CSS class
titlecan be used to give the field a larger text size, suitable for representing page titles and section headings.
MultiFieldPanel(children, heading="", classname=None)¶
This panel condenses several
FieldPanels or choosers, from a
tuple, under a single
tupleof child panels
A heading for the fields
Collapsing MultiFieldPanels to save space
MultiFieldPanel s are expanded and not collapsible. Adding
classname will enable the collapse control. Adding both
collapsed to the
classname parameter will load the editor page with the
MultiFieldPanel collapsed under its heading.
content_panels = [ MultiFieldPanel( [ ImageChooserPanel('cover'), DocumentChooserPanel('book_file'), PageChooserPanel('publisher'), ], heading="Collection of Book Fields", classname="collapsible collapsed" ), ]
InlinePanel(relation_name, panels=None, classname='', heading='', label='', help_text='', min_num=None, max_num=None)¶
This panel allows for the creation of a “cluster” of related objects over a join to a separate model, such as a list of related links or slides to an image carousel.
This is a powerful but complex feature which will take some space to cover, so we’ll skip over it for now. For a full explanation on the usage of
InlinePanel, see Inline Panels and Model Clusters.
This panel creates a columnar layout in the editing interface, where each of the child Panels appears alongside each other rather than below.
Use of FieldRowPanel particularly helps reduce the “snow-blindness” effect of seeing so many fields on the page, for complex models. It also improves the perceived association between fields of a similar nature. For example if you created a model representing an “Event” which had a starting date and ending date, it may be intuitive to find the start and end date on the same “row”.
By default, the panel is divided into equal-width columns, but this can be overridden by adding
col*class names to each of the child Panels of the FieldRowPanel. The Wagtail editing interface is laid out using a grid system, in which the maximum width of the editor is 12 columns. Classes
col12can be applied to each child of a FieldRowPanel. The class
col3will ensure that field appears 3 columns wide or a quarter the width.
col4would cause the field to be 4 columns wide, or a third the width.

PageChooserPanel(field_name, page_type=None, can_choose_root=False)¶
from wagtail.core.models import Page from wagtail.admin.edit_handlers import PageChooserPanel class BookPage(Page): related_page = models.ForeignKey( 'wagtailcore.Page', null=True, blank=True, on_delete=models.SET_NULL, related_name='+', ) content_panels = Page.content_panels + [ PageChooserPanel('related_page', 'demo.PublisherPage'), ]
PageChooserPaneltakes one required argument, the field name. Optionally, specifying a page type (in the form of an
"appname.modelname"string) will filter the chooser to display only pages of that type. A list or tuple of page types can also be passed in, to allow choosing a page that matches any of those page types:
PageChooserPanel('related_page', ['demo.PublisherPage', 'demo.AuthorPage'])
can_choose_root=Truewill allow the editor to choose the tree root as a page. Normally this would be undesirable, since the tree root is never a usable page, but in some specialised cases it may be appropriate; for example, a page with an automatic “related articles” feed could use a PageChooserPanel to select which subsection articles will be taken from, with the root corresponding to ‘everywhere’.
Wagtail includes a unified image library, which you can access in your models through the
Imagemodel and the
ImageChooserPanelchooser. Here’s how:
from wagtail.images.models import Image from wagtail.images.edit_handlers import ImageChooserPanel class BookPage(Page): cover = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) content_panels = Page.content_panels + [ ImageChooserPanel('cover'), ]
Django’s default behaviour is to “cascade” deletions through a ForeignKey relationship, which may not be what you want. This is why the
on_deleteparameters should be set to allow for an empty field. (See Django model field reference (on_delete) ).
ImageChooserPaneltakes only one argument: the name of the field.
Imageobjects in a template requires the use of a template tag. See Using images in templates.
This panel adds a single, read-only section in the edit interface for pages implementing the
AbstractFormmodel. It includes the number of total submissions for the given form and also a link to the listing of submissions.
from wagtail.contrib.forms.models import AbstractForm from wagtail.contrib.forms.edit_handlers import FormSubmissionsPanel class ContactFormPage(AbstractForm): content_panels = [ FormSubmissionsPanel(), ]
For files in other formats, Wagtail provides a generic file store through the
from wagtail.documents.models import Document from wagtail.documents.edit_handlers import DocumentChooserPanel class BookPage(Page): book_file = models.ForeignKey( 'wagtaildocs.Document', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) content_panels = Page.content_panels + [ DocumentChooserPanel('book_file'), ]
As with images, Wagtail documents should also have the appropriate extra parameters to prevent cascade deletions across a ForeignKey relationship.
DocumentChooserPaneltakes only one argument: the name of the field.
Changed in version 1.1: Before Wagtail 1.1, it was necessary to pass the snippet model class as a second parameter to
SnippetChooserPanel. This is now automatically picked up from the field.
Snippets are vanilla Django models you create yourself without a Wagtail-provided base class. A chooser,
SnippetChooserPanel, is provided which takes the field name as an argument.
from wagtail.snippets.edit_handlers import SnippetChooserPanel class BookPage(Page): advert = models.ForeignKey( 'demo.Advert', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) content_panels = Page.content_panels + [ SnippetChooserPanel('advert'), ]
See Snippets for more information.
Built-in Fields and Choosers¶
Django’s field types are automatically recognised and provided with an appropriate widget for input. Just define that field the normal Django way and pass the field name into
FieldPanel when defining your panels. Wagtail will take care of the rest.
Here are some Wagtail-specific types that you might include as fields in your models.
By adding CSS classes to your panel definitions or adding extra parameters to your field definitions, you can control much of how your fields will display in the Wagtail page editing interface. Wagtail’s page editing interface takes much of its behaviour from Django’s admin, so you may find many options for customisation covered there. (See Django model field reference ).
classname="full" to make a field (input element) stretch the full width of the Wagtail page editor. This will not work if the field is encapsulated in a
MultiFieldPanel, which places its child fields into a formset.
classname="title" to make Page’s built-in title field stand out with more vertical padding.
To make input or chooser selection mandatory for a field, add
blank=False to its model definition. (See Django model field reference (blank) ).
Without a panel definition, a default form field (without label) will be used to represent your fields. If you intend to hide a field on the Wagtail page editor, define the field with
editable=False (See Django model field reference (editable) ).
Inline Panels and Model Clusters¶
django-modelcluster module allows for streamlined relation of extra models to a Wagtail page. For instance, you can create objects related through a
ForeignKey relationship on the fly and save them to a draft revision of a
Page object. Normally, your related objects “cluster” would need to be created beforehand (or asynchronously) before linking them to a Page.
Let’s look at the example of adding related links to a
Page-derived model. We want to be able to add as many as we like, assign an order, and do all of this without leaving the page editing screen.
from wagtail.core.models import Orderable, Page from modelcluster.fields import ParentalKey # The abstract model for related links, complete with panels class RelatedLink(models.Model): title = models.CharField(max_length=255) link_external = models.URLField("External link", blank=True) panels = [ FieldPanel('title'), FieldPanel('link_external'), ] class Meta: abstract = True # The real model which combines the abstract model, an # Orderable helper class, and what amounts to a ForeignKey link # to the model we want to add related links to (BookPage) class BookPageRelatedLinks(Orderable, RelatedLink): page = ParentalKey('demo.BookPage', on_delete=models.CASCADE, related_name='related_links') class BookPage(Page): # ... content_panels = Page.content_panels + [ InlinePanel('related_links', label="Related Links"), ]
RelatedLink class is a vanilla Django abstract model. The
BookPageRelatedLinks model extends it with capability for being ordered in the Wagtail interface via the
Orderable class as well as adding a
page property which links the model to the
BookPage model we’re adding the related links objects to. Finally, in the panel definitions for
BookPage, we’ll add an
InlinePanel to provide an interface for it all. Let’s look again at the parameters that
InlinePanel( relation_name, panels=None, heading='', label='', help_text='', min_num=None, max_num=None )
relation_name is the
related_name label given to the cluster’s
ParentalKey relation. You can add the
panels manually or make them part of the cluster model.
help_text provide a heading and caption, respectively, for the Wagtail editor.
label sets the text on the add button, and is used as the heading when
heading is not present. Finally,
max_num allow you to set the minimum/maximum number of forms that the user must submit.
Changed in version 1.0: In previous versions, it was necessary to pass the base model as the first parameter to
InlinePanel; this is no longer required.
