# Editor Toolbar

> A rich-text formatting toolbar: undo/redo, a block menu that previews each style, bold/italic/underline/strike/code toggles, link, a highlighter with swatches, lists and alignment, with tooltips naming every shortcut. Groups fold into a More menu as it narrows. Editor-agnostic: pass state, handle onAction with Tiptap, Lexical or your own. Base UI Toolbar with roving arrow keys.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/editor-toolbar/editor-toolbar.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/editor-toolbar
```

Registry item JSON: https://www.assembli.design/r/editor-toolbar.json (send `Authorization: Bearer <api key>`)
