The description of the custom field, which is displayed in Jira.

The type of the custom field. These built-in custom field types are available:

cascadingselect: Enables values to be selected from two levels of select lists (value: com.atlassian.jira.plugin.system.customfieldtypes:cascadingselect) datepicker: Stores a date using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:datepicker) datetime: Stores a date with a time component (value: com.atlassian.jira.plugin.system.customfieldtypes:datetime) float: Stores and validates a numeric (floating point) input (value: com.atlassian.jira.plugin.system.customfieldtypes:float) grouppicker: Stores a user group using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:grouppicker) importid: A read-only field that stores the ID the issue had in the system it was imported from (value: com.atlassian.jira.plugin.system.customfieldtypes:importid) labels: Stores labels (value: com.atlassian.jira.plugin.system.customfieldtypes:labels) multicheckboxes: Stores multiple values using checkboxes (value: ) multigrouppicker: Stores multiple user groups using a picker control (value: ) multiselect: Stores multiple values using a select list (value: com.atlassian.jira.plugin.system.customfieldtypes:multicheckboxes) multiuserpicker: Stores multiple users using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:multigrouppicker) multiversion: Stores multiple versions from the versions available in a project using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:multiversion) project: Stores a project from a list of projects that the user is permitted to view (value: com.atlassian.jira.plugin.system.customfieldtypes:project) radiobuttons: Stores a value using radio buttons (value: com.atlassian.jira.plugin.system.customfieldtypes:radiobuttons) readonlyfield: Stores a read-only text value, which can only be populated via the API (value: com.atlassian.jira.plugin.system.customfieldtypes:readonlyfield) select: Stores a value from a configurable list of options (value: com.atlassian.jira.plugin.system.customfieldtypes:select) textarea: Stores a long text string using a multiline text area (value: com.atlassian.jira.plugin.system.customfieldtypes:textarea) textfield: Stores a text string using a single-line text box (value: com.atlassian.jira.plugin.system.customfieldtypes:textfield) url: Stores a URL (value: com.atlassian.jira.plugin.system.customfieldtypes:url) userpicker: Stores a user using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:userpicker) version: Stores a version using a picker control (value: com.atlassian.jira.plugin.system.customfieldtypes:version)

To create a field based on a Forge custom field type, use the ID of the Forge custom field type as the value. For example, ari:cloud:ecosystem::extension/e62f20a2-4b61-4dbe-bfb9-9a88b5e3ac84/548c5df1-24aa-4f7c-bbbb-3038d947cb05/static/my-cf-type-key.

The searcher defines the way the field is searched in Jira. For example, com.atlassian.jira.plugin.system.customfieldtypes:grouppickersearcher. The search UI (basic search and JQL search) will display different operations and values for the field, based on the field searcher. You must specify a searcher that is valid for the field type, as listed below (abbreviated values shown):

cascadingselect: cascadingselectsearcher datepicker: daterange datetime: datetimerange float: exactnumber or numberrange grouppicker: grouppickersearcher importid: exactnumber or numberrange labels: labelsearcher multicheckboxes: multiselectsearcher multigrouppicker: multiselectsearcher multiselect: multiselectsearcher multiuserpicker: userpickergroupsearcher multiversion: versionsearcher project: projectsearcher radiobuttons: multiselectsearcher readonlyfield: textsearcher select: multiselectsearcher textarea: textsearcher textfield: textsearcher url: exacttextsearcher userpicker: userpickergroupsearcher version: versionsearcher

If no searcher is provided, the field isn't searchable. However, Forge custom fields have a searcher set automatically, so are always searchable.
