The rule editor's field dropdown shows Rating, Pick Flag, Color Label and
Any Searchable Text at the top, then a separator and one submenu per
field group instead of one long flat list. The group holding the current
field is shown in bold. Picking a field from a submenu closes the menu
and keeps the operator only when the new field has it. Widget ids
ruleField / ruleFieldGroup / ruleFieldItem let the control channel drive
it, and group names join the i18n display-label gap report.
