Textbox.io has an enhanced spell-checking feature which requires the use of a Java-based server-side component.

If you choose not to deploy the Textbox.io spell checking service, then Textbox.io will fall back to using the browser's spell checker where available.

To enable the Spelling service on a compatible Java server:

  1. Deploy the Spelling services.  See Server-Side Components and Spell Checking for service deployment instructions.
  2. Set the SpellingUrl control property to point to the spelling service.
  3. Add your production and development servers to the "allowed origins" list.  See Setting ports for development server for more information.
