Is this feature still on the cards? I’m just working on some models which represent long pages with lots of sections, and due to the low contrast of Dato’s form UI (both in terms colour, and sizing and spacing), it’s really really hard to scan the page and see which field you’re after.
The project isn’t public so I can’t share, but you can imagine a long page with 30+ fields of all sorts, text, multiline, galleries, seo, modular, etc.
Improved colour and size contrast, vertical separators elements, etc could all help. But I agree with the above that the most straightforward solution is horizontal tabs across the top. The content of each tab wouldn’t get too long, and users would understand what each tab is for with a simple text label.
It would also allow us to train users what to expect in different models — eg. if a model has an associated SEO field, then it’s always the first tab on the left labelled ‘metadata’ with a title and summary field.
