Hi Chef , just a heads up that the ajax call for drop down boxes does not seem to be working on these versions. It does not group correctly and selects all the available data rather than grouping it by the first selected item..
The ajax call works in 3.0.10 but unfortunately the tabs don't work and modal pop up selection comes up blank.
This has been tested within your sandbox and externally.
I have refreshed my browser, checked all versions and removed fields and then re -entered to check if it was something I had done. Doesn't appear to be.
over to you Chef.
