Hi Peter,
Thanks for looking at this.
I did try that initially, and I was able to style the form correctly, but the issue with using groups is that it changes how the data is saved in the db. The CPT already has data in it, so I need a layout that only wraps the fields in a DIV. but they are still saved as individual meta keys and values.
But, I had a look at your links and that reminded me of the before and after options. I can use them to add in a div, around the fields I want to group, so I guess it's not needed. It would look nice though, if you could see the grouping in the designer 😉
Thanks for your help
Ger
