Footer#
We customize the footer using component shadowing as well, by copying the original Volto Footer component from the omelette folder (omelette/src/components/theme/Footer/Footer.jsx) into the customizations/components/theme/Footer/Footer.jsx file.
Since we need the Logo component in the Footer, we import it from Volto as we did in the Header:
import { Logo } from '@plone/volto/components';
We also need the Grid component from Semantic UI:
import { Container, List, Grid } from 'semantic-ui-react';
Then, we replace the Footer component content to match the one from plone.org.
