# Plate editor Notion-style activity content editing with the content-plate plugin. `@headless-lms/content-plate` is the [Plate](https://platejs.org)-based implementation of the swappable activity content editor. It default-exports an `EditorModule` satisfying `@headless-lms/editor`; the content blob is the Plate node array, stored opaquely by the backend — the server never interprets it. ## What's included - **Text blocks** — paragraphs, headings, blockquote, code blocks with syntax highlighting, bulleted/numbered/to-do lists, toggle, callout, columns, tables, dates, emoji, links, font and background color. - **Media** — image, video, audio, file and URL embeds, with captions, resize, preview, and upload placeholders (uploads go through the [storage adapter](/docs/adapters/storage/minio)'s presigned URLs). - **Notion-style UX** — `/` slash command menu, drag handles and drop targets, multi-block selection, right-click block context menu (turn into, color, align, duplicate, delete), floating formatting toolbar, and autoformat shortcuts (`#`, `>`, ` ``` `, `-`, …). ## Swapping the editor The editor is behind `@headless-lms/editor`: an `EditorModule` bundles the client-side `Editor`, an RSC-safe `Renderer`, a `validate` function, and `meta: { type, version }` identifying the content format. Implement the contract and register your module in the frontend to replace Plate entirely — existing content keeps working as long as your module declares the format it can render.
