Panel types

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.

FieldPanel

class wagtail.admin.panels.FieldPanel(field_name, classname=None, widget=None, heading='', disable_comments=False, permission=None)

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).

disable_comments(optional)

This allows you to prevent a field level comment button showing for this panel if set to True (see Commenting).

permission(optional)

Allows a field to be selectively shown to users with sufficient permission. Accepts a permission codename such as 'myapp.change_blog_category' - if the logged-in user does not have that permission, the field will be omitted from the form. See Django’s documentation on custom permissions for details on how to set permissions up; alternatively, if you want to set a field as only available to superusers, you can use any arbitrary string (such as 'superuser') as the codename, since superusers automatically pass all permission tests.

StreamFieldPanel

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

Deprecated; use FieldPanel instead.

Changed in version 3.0: StreamFieldPanel is no longer required for StreamField.

MultiFieldPanel

class wagtail.admin.panels.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

InlinePanel

class wagtail.admin.panels.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.

Collapsing InlinePanels to save space

Note that you can use classname="collapsible collapsed" to load the panel collapsed under its heading in order to save space in the Wagtail admin. See Collapsible for more details on collapsible usage.

FieldRowPanel

class wagtail.admin.panels.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.panels.HelpPanel(content='', template='wagtailadmin/panels/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.panels.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.models import Page
from wagtail.admin.panels 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’.

Changed in version 3.0: FieldPanel now also provides a page chooser interface for foreign keys to page models. PageChooserPanel is only required when specifying the page_type or can_choose_root parameters.

ImageChooserPanel

class wagtail.images.edit_handlers.ImageChooserPanel(field_name)

Deprecated; use FieldPanel instead.

Changed in version 3.0: ImageChooserPanel is no longer required to obtain an image chooser interface.

FormSubmissionsPanel

class wagtail.contrib.forms.panels.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.panels import FormSubmissionsPanel

class ContactFormPage(AbstractForm):
    content_panels = [
        FormSubmissionsPanel(),
    ]

DocumentChooserPanel

class wagtail.documents.edit_handlers.DocumentChooserPanel(field_name)

Deprecated; use FieldPanel instead.

Changed in version 3.0: DocumentChooserPanel is no longer required to obtain a document chooser interface.

SnippetChooserPanel

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

Deprecated; use FieldPanel instead.

Changed in version 3.0: SnippetChooserPanel is no longer required to obtain a document chooser interface.

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.

Collapsible

By default, panels are expanded and not collapsible. Use classname="collapsible" to enable the collapse control. Use classname="collapsible collapsed" will load the editor page with the panel collapsed under its heading.

You must define a heading when using collapsible with MultiFieldPanel. You must define a heading or label when using collapsible with InlinePanel.

    content_panels = [
        MultiFieldPanel(
            [
                FieldPanel('cover'),
                FieldPanel('book_file'),
                FieldPanel('publisher'),
            ],
            heading="Collection of Book Fields",
            classname="collapsible collapsed"
        ),
    ]

Placeholder Text

By default, Wagtail uses the field’s label as placeholder text. To change it, pass to the FieldPanel a widget with a placeholder attribute set to your desired text. You can select widgets from Django’s form widgets, or any of the Wagtail’s widgets found in wagtail.admin.widgets.

For example, to customise placeholders for a Book model exposed via ModelAdmin:

# models.py
from django import forms            # the default Django widgets live here
from wagtail.admin import widgets   # to use Wagtail's special datetime widget

class Book(models.Model):
    title = models.CharField(max_length=256)
    release_date = models.DateField()
    price = models.DecimalField(max_digits=5, decimal_places=2)

    # you can create them separately
    title_widget = forms.TextInput(
        attrs = {
            'placeholder': 'Enter Full Title'
        }
    )
    # using the correct widget for your field type and desired effect
    date_widget = widgets.AdminDateInput(
        attrs = {
            'placeholder': 'dd-mm-yyyy'
        }
    )

    panels = [
        FieldPanel('title', widget=title_widget), # then add them as a variable
        FieldPanel('release_date', widget=date_widget),
        FieldPanel('price', widget=forms.NumberInput(attrs={'placeholder': 'Retail price on release'})) # or directly inline
    ]

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.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.

For another example of using model clusters, see Tagging.
