What are Zone Fields?
There are different ways to describe what a Zone Field is and how it works.
A Zone Field is a JIRA Customfield
The Zone Field is a JIRA Customfield. Therefore it is effected by ordinary JIRA configuration like every other Customfield. This includes JIRA Screen, Issue Type, Workflow configuration and many more. More specifically a Zone Field is a group Customfield, and therefore can be used in places where a Customfield containing a group can be referred to (Permissions, Issue Security Schemes).
The Zone Field also provides a searcher, such that searching and filtering is possible.
A Zone Field displays as a Select Box containing Zones to the User
When viewed on the "Edit Issue" or "Create Issue"-Screen the Zone Field is displayed as a Select Box to the user.
A Zone Field controls the content of Dependent Zone Fields
The celix Zones Plugin provides additional Customfields, which change their possible values when a zone is selected. For example you can search via auto-complete for users which are in the currently selected zone.
A Zone Field offers access to Zones of a common type
The name of the Zone Field may be something like: "Customer", "Tenant", "Product" or "Team". This is also the type of Zones in the Field. If you want to partition your JIRA for your Customers you will want to have the Zone name contain the customers name and the Zone Field name to be something like "Customer or "Tenant. If you want to partition your JIRA for different type of Zones you will want to create multiple Zone Fields.
A Zone Field may show different Zones in different Projects
It is possible to configure which Zones are enabled in which JIRA Projects. The Zone Field will only show enabled Zones, depending on the project it is used.
A Zone Field may be only edited by Users in specific Project Roles
You can specify if you want the Zone Field to be editable after initially selecting a Zone at creation. You can even control if you want to allow this on a project role basis.
A Zone Field may only display specific Zones to authorized Users
It is possible to allow users to only see Zones in Zone Field, which they are member of.
