Recipes#

This chapter provides several recipes to working with the Classic UI in Plone 6.

Add custom classes to the body element#

Body classes are generated in the LayoutPolicy.bodyClass method in the module plone.app.layout.globals.layout. It allows you to create your own body-classes using named adapters.

First create a class as follows.

from plone.app.layout.globals.interfaces import IBodyClassAdapter

@implementer(IBodyClassAdapter)
class CustomBodyClasses(object):
    """Additional body classes adapter."""
    def __init__(self, context, request):
        self.context = context
        self.request = request

    def get_classes(self, template, view):
        return ["additional-class", "another-css-class"]

Then register the adapter in ZCML.

<adapter
    factory=".custombodyclasses.CustomBodyClasses"
    for="* *"
    name="myproject-customclasses"
/>

Customize pattern_options#

The following example shows how to customize the Favorites menu in the contentbrowser pattern.

First create a multiadapter as shown.

from plone import api
from plone.app.z3cform.interfaces import IContentBrowserWidget
from plone.dexterity.interfaces import IDexterityContent
from z3c.form.interfaces import IForm
from z3c.form.interfaces import IValue
from zope.component impport adapter
from zope.interface import implementer
from zope.publisher.interfaces import  IRequest
from zope.schema.interfaces import IField

@implementer(IValue)
@adapter(IDexterityContent, IRequest, IForm, IField, IContentBrowserWidget)
class ContentbrowserPatternOptions:

    def __init__(self, context, request, form, field, widget):
        self.context = context
        self.request = request
        self.form = form
        self.field = field
        self.widget = widget

    def get(self):
        portal_path = "/".join(api.portal.get().getPhysicalPath())
        return {
            "favorites": [
                {"title": "my favorite folder", "path": f"{portal_path}/path/to/my/favorite/folder"},
                {"title": "Portal", "path": portal_path},
            ],
        }

Then register it with ZCML as shown.

<adapter factory=".ContentbrowserPatternOptions"
         name="pattern_options">
