I noticed I had a simple bool drop down
Yes / No that does not work
config => JQuery, table, maximum
Bool Field settings were
Control = Combo
Display = Yes / No
Required = (tested both checked and unchecked)
But - I noticed the radio buttons worked
Just fine
For the combo box
The null value is displayed at the top of the drop down list but yes and no are missing
Also seen a green message prompt box that was covering one of my combo drop downs upon page load
when default value was undefined (information message was defined)
Unsure if its related but thought i would add as it as to do with combo and "hidden" mentioned above
