The ComboBoxInput class defines the desired user interface for a combo box group.

Coded-value domains are required when using this input type. Previously, fields containing values that weren't compatible with their associated coded-value domain(s) displayed the option and would remove it once a user updated the value. The ComboBoxInput will now display and keep the value but will disable it.
