It’s possible to connect a Greenlight query-like menu, pricelist, or anything, to a Google sheet. The Google speedtest is, despite fetching the data from Google, still 90 on mobile and desktop (without cache).
This menu has a live link to a Google spreadsheet. Just change the spreadsheet and within minutes (or seconds…) your website shows the changed menu or pricelist. If you want to show an image, just place the full URL (including https://) in the Google sheet field.
This is just an example of a page with the content (title, subtitle, bodytext) from Google sheet. Just change the spreadsheet and within minutes (or seconds…) your website shows the changed content. For images to show, just place the full URL (including https://) in the Google sheet field.
