WordPress Widgets are handy little modules that enable you to add specific functionality to sidebars and footers of our themes. You don’t need to know any coding to use widgets. Thanks to WordPress, you can use your sidebars to display images, recent posts, a search bar, and much more.

POPCORN in total has 8 sidebars and uses classic widgets instead of gutenberg blocks. You can move widgets to sidebars using drag and drop from Customizer or jsut jump to the POPCORN -> Widgets & Sidebars
