Shortcodes are not natively supported in Drupal 8, so you will need to install a module to use them. Here are the steps to add shortcodes to Drupal 8:
1. Install the “Shortcode” module from the Drupal.org repository (https://www.drupal.org/project/shortcode).
1. Enable the module by going to the “Extend” page and checking the box beside “Shortcode.”
1. Once the module is enabled, you can add shortcode tags in any content type that supports the text format toolbar.
1. To add a shortcode, enter the tag in square brackets, like this: [shortcode\_tag]
1. You can also add attributes to the shortcode tag, like this: [shortcode\_tag attribute=“value”]
1. To create a custom shortcode, go to the Shortcode Configuration page and enter the name of the shortcode you want to create, along with the HTML or PHP code you want to use.
1. Save your changes and your custom shortcode will be available for use in your content.
That’s it! You can now use shortcodes on your Drupal 8 site.
