Supported custom field types

This page provides a comprehensive reference for mapping Jira custom field types to Simple Issue Language (SIL™ ) data types, enabling developers to properly handle custom field data in their SIL scripts.

Standard field types reference

SIL automatically converts custom field values to SIL data types following established mapping patterns. The table below lists all supported standard field types and their corresponding SIL representations:

Contents: 1 Standard field types reference 2 Product-specific fields

Group name	Custom field type	SIL data type	Usage and notes

Group name	Custom field type	SIL data type	Usage and notes
Date and time fields	DateTime	`date`	Supports full DateTime with timezone
Date and time fields	DatePicker	`date`	Date only, Time component is ignored
Numeric fields	Number field	`number`	Supports both integers and decimals
Text-based fields	URL field	`string`	Stores complete URL as text
	Text field	`string`	Single-line text input
	Textarea	`string`	Multi-line text input Test formatting behavior in your specific Jira environment.
User and group fields	User Picker	`string`	Stores username (not full name)
	Multi User Picker	`string []`	String array of usernames
	Group Picker	`string`	Group name as string
	Multi Group Picker	`string []`	String array of group names
Selection fields	Multi Checkboxes	`string []`	String array of selected values
	Multi Select	`string []`	String array of selected options
	Radio Buttons	`string`	Single selected value
	Select List	`string`	Single selected option
	Cascading Select	`string []`	Two-element array: [parent, child] Setting an invalid parent-child combination will be rejected. When you assign a single value to a cascading select field in SIL, it will be treated as the parent/root selection only.
Project and version fields	Project Picker	`string`	Project key
	Version field	`string`	Version name as string
	Multi Version field	`string []`	String array of version names
	Labels Field	`string []`	Array of label strings

Product-specific fields

Product name	Notes

Product name	Notes
Jira Service Management (JSM) fields	JSM custom fields are supported with the same type mappings as standard fields. Special fields like SLA data and request participant fields are accessible through dedicated SIL functions.
Jira Software fields	Agile fields, such as Sprint and Story Points, are directly accessible like standard custom fields. No special handling required.
Portfolio for Jira fields	Portfolio-specific fields can be accessed using the same patterns as standard custom fields.
