Is there any API to list out all custom options for a custom field (Single select list)?

Mani Chellamuth

I need to retrieve all custom options for a custom field using Jira API.

customField.getValue() will retrieve stored value for a issue. But I need all values of a custom field for validation.

FieldConfig config = customField.getRelevantConfig(issue);
Options options = optionsManager.getOptions(config);
List<Option> optionList = options.getRootOptions();
