# Customising snippets
Additional customisations for each snippet model can be achieved through a custom {class}`~wagtail.snippets.views.snippets.SnippetViewSet` class. This allows you to customise the listing view (e.g. adding custom columns, filters), create a custom menu item, and more.
Before proceeding, ensure that you register the snippet model using `register_snippet` as a function instead of a decorator, as described in [](wagtailsnippets_registering).

# Customising admin views for snippets
Additional customisations to the admin views for each snippet model can be achieved through a custom {class}`~wagtail.snippets.views.snippets.SnippetViewSet` class. This allows you to customise the listing view (e.g. adding custom columns, filters), create a custom menu item, and more.
Before proceeding, ensure that you register the snippet model using `register_snippet` as a function instead of a decorator, as described in [](wagtailsnippets_registering).
For demonstration, consider the following `Member` model and a `MemberFilterSet` class:

You can define a {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.icon` attribute to specify the icon that is used across the admin for this snippet type. The `icon` needs to be [registered in the Wagtail icon library](../../advanced_topics/icons). If `icon` is not set, the default `"snippet"` icon is used.
## Icon
The {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.admin_url_namespace` attribute can be set to use a custom URL namespace for the URL patterns of the views. If unset, it defaults to `wagtailsnippets_{app_label}_{model_name}`. Meanwhile, setting {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.base_url_path` allows you to customise the base URL path relative to the Wagtail admin URL. If unset, it defaults to `snippets/app_label/model_name`. If you need further customisations, you can also override the {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_admin_url_namespace` and {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_admin_base_path` methods to override the namespace and base URL path, respectively.
You can define an {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.icon` attribute on the `SnippetViewSet` to specify the icon that is used across the admin for this snippet type. The `icon` needs to be [registered in the Wagtail icon library](../../advanced_topics/icons). If `icon` is not set, the default `"snippet"` icon is used.
## URL namespace and base URL path
The {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.admin_url_namespace` attribute can be set to use a custom URL namespace for the URL patterns of the views. If unset, it defaults to `wagtailsnippets_{app_label}_{model_name}`. Meanwhile, setting {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.base_url_path` allows you to customise the base URL path relative to the Wagtail admin URL. If unset, it defaults to `snippets/app_label/model_name`.
If you need further customisations, you can also override the {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_admin_url_namespace` and {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_admin_base_path` methods to override the namespace and base URL path, respectively.
Similar URL customisations are also possible for the snippet chooser views through {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.chooser_admin_url_namespace`, {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.chooser_base_url_path`, {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_chooser_admin_url_namespace`, and {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_chooser_admin_base_path`.
## Listing view
The {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.list_display` attribute can be set to specify the columns shown on the listing view. To customise the number of items to be displayed per page, you can set the {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.list_per_page` attribute (or {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.chooser_per_page` for the chooser listing).
To customise the base queryset for the listing view, you could override the {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_queryset` method. Additionally, the {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.ordering` attribute can be used to specify the default ordering of the listing view.
You can add the ability to filter the listing view by defining a {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.list_filter` attribute and specifying the list of fields to filter. Wagtail uses the django-filter package under the hood, and this attribute will be passed as django-filter's `FilterSet.Meta.fields` attribute. This means you can also pass a dictionary that maps the field name to a list of lookups. If you would like to customise it further, you can also use a custom `wagtail.admin.filters.WagtailFilterSet` subclass by overriding the {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.filterset_class` attribute. The `list_filter` attribute is ignored if `filterset_class` is set. For more details, refer to [django-filter's documentation](https://django-filter.readthedocs.io/en/stable/guide/usage.html#the-filter).

@ -110,7 +118,7 @@ The ability to have a separate menu item was added.
By default, registering a snippet model will add a "Snippets" menu item to the sidebar menu. You can configure a snippet model to have its own top-level menu item in the sidebar menu by setting {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.add_to_admin_menu` to `True`. Alternatively, if you want to add the menu item inside the Settings menu, you can set {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.add_to_settings_menu` to `True`. The menu item will use the icon specified on the `SnippetViewSet` and it will link to the index view for the snippet model.
Unless specified, the menu item will be named after the model's verbose name. You can customise the menu item's label, name, and order by setting the {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.menu_label`, {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.menu_icon`, and {attr}`~wagtail.snippets.views.snippets.SnippetViewSet.menu_order` attributes respectively. If you would like to customise the `MenuItem` instance completely, you could override the {meth}`~wagtail.snippets.views.snippets.SnippetViewSet.get_menu_item` method.
