In WordPress, full site editing (FSE) is a feature that allows users to customize and edit every aspect of their website’s design, including headers, footers, sidebars, and other template parts, directly within the WordPress editor. Groups in FSE refer to logical containers that hold various blocks or elements together within a template. They help organize the layout and structure of a webpage.
Groups can contain a combination of blocks such as text blocks, image blocks, navigation blocks, etc., and they can be styled collectively. This allows for easier management of complex layouts by grouping related content together. For example, you might have a group for the header containing the site title, logo, and navigation menu, and another group for the footer containing copyright information and social media links.
Using groups in full site editing simplifies the process of designing and customizing templates, making it more intuitive for users to create cohesive and visually appealing websites directly within the WordPress interface.
