public function IngredientUnitUtility::createUnitSelectOptions in Recipe 8.2

Returns options for a unit select form element.

@todo The blank option should be created as the #empty_option in the individual select elements. Unfortunately, the default_unit element in the field settings form uses a #process function to set its options which seems to overwrite the #empty_option. Even setting the #empty_option during the #process step doesn't seem to work. This seems like a possible core bug and will probably have to be fixed there before we can complete this task.

Parameters

array $units: An array of units.

Return value

array An array of unit key/value pairs for use as select form element options.
