Available panel types¶

FieldPanel¶

class wagtail.admin.edit_handlers.FieldPanel(field_name, classname=None, widget=None, heading='')¶

This is the panel used for basic Django field types.

field_name¶: This is the name of the class property used in your model definition.

classname¶

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 full can be used to format the panel so it covers the full width of the Wagtail page editor.

The CSS class title can be used to give the field a larger text size, suitable for representing page titles and section headings.

widget(optional)¶: This parameter allows you to specify a Django form widget to use instead of the default widget for this field type.

heading(optional)¶: This allows you to override the heading for the panel, which will otherwise be set automatically using the form field’s label (taken in turn from a model field’s verbose_name).

StreamFieldPanel¶

class wagtail.admin.edit_handlers.StreamFieldPanel(field_name, classname=None, widget=None)¶

This is the panel used for Wagtail’s StreamField type (see Freeform page content using StreamField).

FieldPanel.field_name¶: This is the name of the class property used in your model definition.

FieldPanel.classname(optional)¶

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 full can be used to format the panel so it covers the full width of the Wagtail page editor.

MultiFieldPanel¶

class wagtail.admin.edit_handlers.MultiFieldPanel(children, heading="", classname=None)¶

This panel condenses several FieldPanel s or choosers, from a list or tuple, under a single heading string.

children¶: A list or tuple of child panels

heading¶: A heading for the fields

Collapsing MultiFieldPanels to save space

By default, MultiFieldPanel s are expanded and not collapsible. Adding collapsible to classname will enable the collapse control. Adding both collapsible and 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¶

class wagtail.admin.edit_handlers.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.

FieldRowPanel¶

class wagtail.admin.edit_handlers.FieldRowPanel(children, classname=None)¶

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 col1-col12 can be applied to each child of a FieldRowPanel. The class col3 will ensure that field appears 3 columns wide or a quarter the width. col4 would cause the field to be 4 columns wide, or a third the width.

children¶: A list or tuple of child panels to display on the row

classname¶: A class to apply to the FieldRowPanel as a whole

HelpPanel¶

class wagtail.admin.edit_handlers.HelpPanel(content='', template='wagtailadmin/edit_handlers/help_panel.html', heading='', classname='')¶

content¶: HTML string that gets displayed in the panel.

template¶: Path to a template rendering the full panel HTML.

heading¶: A heading for the help content.

classname¶: String of CSS classes given to the panel which are used in formatting and scripted interactivity.

PageChooserPanel¶

class wagtail.admin.edit_handlers.PageChooserPanel(field_name, page_type=None, can_choose_root=False)¶

You can explicitly link Page-derived models together using the Page model and PageChooserPanel.

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'),
    ]

PageChooserPanel takes 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'])

Passing can_choose_root=True will 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’.

ImageChooserPanel¶

class wagtail.images.edit_handlers.ImageChooserPanel(field_name)¶

Wagtail includes a unified image library, which you can access in your models through the Image model and the ImageChooserPanel chooser. 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 null, blank, and on_delete parameters should be set to allow for an empty field. ImageChooserPanel takes only one argument: the name of the field.

Displaying Image objects in a template requires the use of a template tag. See Using images in templates.

FormSubmissionsPanel¶

class wagtail.contrib.forms.edit_handlers.FormSubmissionsPanel¶

This panel adds a single, read-only section in the edit interface for pages implementing the AbstractForm model. 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(),
    ]

DocumentChooserPanel¶

class wagtail.documents.edit_handlers.DocumentChooserPanel(field_name)¶

For files in other formats, Wagtail provides a generic file store through the Document model:

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. DocumentChooserPanel takes only one argument: the name of the field.

SnippetChooserPanel¶

class wagtail.snippets.edit_handlers.SnippetChooserPanel(field_name, snippet_type=None)¶

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.

Field Customisation¶

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).

Full-Width Input¶

Use 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.

Titles¶

Use classname="title" to make Page’s built-in title field stand out with more vertical padding.

Required Fields¶

To make input or chooser selection mandatory for a field, add blank=False to its model definition.

Hiding Fields¶

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.

Inline Panels and Model Clusters¶

The django-modelcluster module allows for streamlined relation of extra models to a Wagtail page via a ForeignKey-like relationship called ParentalKey. Normally, your related objects “cluster” would need to be created beforehand (or asynchronously) before being linked to a Page; however, objects related to a Wagtail page via ParentalKey can be created on-the-fly and saved to a draft revision of a Page object.

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"),
  ]

The 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 accepts:

InlinePanel( relation_name, panels=None, heading='', label='', help_text='', min_num=None, max_num=None )

The 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. heading and 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, min_num and max_num allow you to set the minimum/maximum number of forms that the user must submit.
