Widgets snippets for WordPress
Snippets for widgets and sidebars: restore the classic widget screen, register new widget areas, remove default widgets and allow shortcodes in text widgets. For classic themes and sites that still lean on sidebars.
Register Extra Widget Areas
Creates additional widget areas, such as a shop sidebar or a blog sidebar, that you can fill under Appearance > Widgets and place with a shortcode or theme hook.
Widget Area Above the Footer
Registers an "Above the Footer" widget area and shows its widgets in a responsive row just above the site footer, in classic and block themes.
Widget Area Below Single Posts
Registers an "After Post Content" widget area and displays it at the end of single posts, without editing theme files.
