Adding a user custom field
Follow the next steps to add a user custom field:
Log on to Jira as an administrator
Go to Administration > Project Team
Click User Custom Fields under Project Team App Configuration
On the User Custom Fields tab, click the Add Custom Field button. The Add User Custom Field screen is displayed
Select the Type of the custom field
Type a Name for the new field. The Name is required and must be unique
You can enter a Description for the new field. The description is optional
Configure the display options. Check Visible on project tab panel if you want the field to be displayed on the Project Team tab of the project. Check Visible on user profile if you want the field to be displayed on the user Profile page
If you chose to add a field of type Multi Value Picker, you can enter the input options of the field in the Add Input Options table. The input options can also be added later by editing the custom field. So it is not required to add all the input options during field creation. Also, you can decide if the users are allowed to add new input options by themselves by checking or unchecking Allow users to add new input options by themselves
When you are done, click the Add button at the bottom of the page to add the new custom field. Once added, the new field is listed in the table from the User Custom Fields tab and it also appears as a new column in the table from the Project Team tab of the Jira projects
Adjust the order of the fields as necessary by using the arrows and then click Save custom fields order
