Umbraco Tiptap Toolbar Extension

What is it?

A Tiptap Toolbar Extension adds buttons or controls to the Rich Text Editor's toolbar. It provides an execute method that runs when clicked, and can indicate active/disabled states. Several "kinds" are available: button (simple toggle), colorPickerButton (color selection), menu (dropdown menu), and styleMenu (style selection dropdown).

Workflow

1. Fetch docs - Use WebFetch on the URLs above
2. Ask questions - Button, menu, or color picker? What action to execute?
3. Generate files - Create manifest + API class based on latest docs
4. Explain - Show what was created and how to test

  alias: 'My.TiptapToolbar.Bold',
  name: 'Bold Toolbar Button',
  api: () => import('./bold.tiptap-toolbar-api.js'),
  forExtensions: ['Umb.Tiptap.Bold'], // Links to the tiptap extension
  meta: {
    alias: 'bold',
    icon: 'icon-bold',
    label: 'Bold',
  },
};

export const manifests = [manifest];

  // Override to customize active state detection
  isActive(editor?: Editor): boolean {
