Most custom field types, such as select lists and text fields, can be rendered in multiple ways. For example, select lists can be rendered either with an autocomplete feature or as a simple, standard drop-down list.
In this recipe, we will be changing the environment field to use Wiki Style Renderer so that we can use wiki markup when entering data.
Proceed with the following steps to change the field renderer option:
Log in to JIRA as a JIRA administrator.
Navigate to Administration | Issues | Field Configurations.
Click on the Configure link for the field configuration used by the project and issue type.
Click on the Renders link for the field to change.
Select the new renderer type from the Active Renderer drop-down list.
Click on Update to apply the change as shown in the following screenshot:
