Shortcodes Ultimate is a Swiss Army knife type of plugin. It can do many things – it “is a comprehensive collection of various visual and functional elements, which you can use in the post editor, text widgets or even in template files. Using Shortcodes Ultimate you can easily create tabs, buttons, boxes, sliders and carousels, responsive videos and much, much more.”
It works with both the Block Editor and the Classic editor. You can embed posts into other posts, create “spoilers” (i.e. view/hide content), retrieve parts of posts or pages via category or tag – the list goes on.
In the Block Editor, the plugin is accessible via the open and close brackets icon- “[ ]” after you select the shortcode block:
In the Classic Editor, it is an option on the tool bar.
After clicking the icon, you will see the entire collection. There is a convenient search bar to help locate what you need, as well as a “Filter by Type” option. The shortcodes marked in red are only available for the premium version of the plugin
