ckeditor_html_embed

This module allows embedding arbitrary HTML snippets in the editor by enabling CKEditor5's HTML Embed feature.

From CKEditor's documentation:

Some examples of content that can be embedded thanks to the HTML embed feature:

• Analytics code (that usually require embedding <script> elements).
• Social page widgets (that also require embedding <script> elements).
• Content embeddable by <iframe> elements.
• HTML media elements such as <audio> and <video>.
• HTML snippets produced by external tools (for example, reports or charts).
• Interactive content that requires a combination of rich HTML and scripts.

This module only supports CKEditor5.
