In order to have the See Menu and Order button published on the restaurant's WordPress-built legacy website, the system provides a piece of HTML code.
When this is added to the website, the "See MENU & Order" button will appear allowing WordPress ordering. This can be accessed from the admin panel under "Publishing" -> "Legacy website".
To generate the HTML code for the "See Menu & Order" button, go to the Setup-> Publishing-> Legacy website section within the web admin panel and click on "Yes", like this:
Check the content of the email and modify as needed, type the email address to which it should be sent (restaurant's website webmaster/developer), and click on "Preview and send" or "I'll do this myself":
Clicking on "I'll do this myself" leads to a screen from which the code can be copied and inserted into the restaurant website code:
Once this is performed, the code remains available at the green link, where restaurants can also find instructions on how to publish in WordPress-built websites.
Here is a more detailed guide on how to perform the installation of the "See Menu and Order" button in WordPress.
