For years, “Widgets” were simple blocks: “Search”, “Recent Posts”, “Categories”. You dragged them to the sidebar and done. With the arrival of the Full Site Editing (FSE) era and block themes, the widget concept has completely changed.

Learn more about WordPress development services at WPPoland. If you want the practical answer first, classic themes still use widget areas, while block themes usually move that work into the Site Editor and template structure.

#1. Classic themes

If you’re using an older theme type (like Astra, GeneratePress, or classic Twenty Twenty-One), you still have access to the Appearance > Widgets menu.

However, even there, since WP 5.8, the Block Editor is used by default. Instead of simple fields, you have the full Gutenberg interface inside the sidebar. You can add anything there: Paragraph, Image, even a Shortcode.

Tip: If you miss the old view, install the official Classic Widgets plugin. It restores the simpler drag-and-drop screen for classic widget areas.

#2. Block themes

In modern themes (like Twenty Twenty-Four or Twenty Twenty-Five) there is no Widgets menu. It’s gone.

Instead, you go to Appearance > Editor. Your entire site is editable.

  • Want to add something to the footer? Open the relevant template part in the Site Editor.
  • Want a sidebar? Build it with layout blocks such as Columns or Group, depending on the theme structure.

#What to choose?

For beginners, the block-based widget experience is usually more flexible because you can add richer content without custom HTML. If you are maintaining an older workflow, the Classic Widgets plugin remains the easier option.
