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.
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’s one of the most popular plugins ever, restoring the simple drag & drop screen.
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? Scroll down and click “Edit footer”.
- Want a sidebar? You need to add a “Columns” block and manually create the sidebar structure.
What to choose?
For beginners, the block editor in widgets gives tremendous power (you can finally easily add an author photo to the sidebar without knowing HTML). For conservatives - the Classic Widgets plugin will be supported for years to come.
