These fields provide specialized functions. For example, the Version Picker field lets you select a version from the current project. If you have any custom fields from third-party add-ons (see the following section), they will also be listed here:
| Custom field type | Description |
| Group Picker (multiple group) | This chooses one or more user groups using a pop-up picker window. |
| Group Picker (single group) | This chooses a user group using a pop-up picker window. |
| Project Picker (single project) | This selects lists displaying the projects that are viewable to the user in the system. |
| Text Field (read only) | This is a read-only text field that does not allow users to set their data. It's only possible to set the data programmatically. |
| User Picker (multiple users) | This chooses one or more users from the user base through a pop-up picker window. |
| Version Picker (multiple versions) | This chooses one or more versions from the available versions in the current project. |
| Version Picker (single version) | This chooses a single version from the available versions in the project. |
As you can see, Jira provides you with a comprehensive list of custom field types. In addition, there are many custom field types developed by third-party vendors (available as plugins or add-ons) that you can add to your Jira to enhance its functionality. These custom fields provide many specialized functionalities, such as automatically calculating values and retrieving data from databases directly or connecting to an external system. Once you install the plugin, the process of adding custom fields from other vendors is mostly the same as adding custom fields shipped with Jira.
The following list shows some examples of add-ons that provide additional useful custom fields. You can find them from the Atlassian Marketplace at https://marketplace.atlassian.com:
- Enhancer Plugin for Jira: This includes a number of custom fields that will automatically display dates when key events occur for an issue; for example, when the issue was last closed
- Toolkit Plugin for Jira: This provides a number of useful custom fields, such as showing statistics on users that participate in a given issue and the date when the issue was last commented on
- nFeed: This provides a suite of custom fields that let you connect to databases, remote files, and web services to retrieve data and display it in Jira
- 21 CFR Part 11 E-Signature: This lets users electronically sign issues in Jira as they work on them, for example, approving an issue to be closed
