Field configuration
As you have already seen, fields are used to capture and display data in JIRA. Fields can also have behaviors, which are defined by field configuration. For each field in JIRA, you can configure its behaviors listed as follows:
Field description: This is the description text that appears under the field when an issue is edited.
Visibility: This determines if a field should be visible or hidden.
Required: This specifies if a field will be optional or required to have a value when an issue is being created/updated. When applied to a select, checkbox, and radio button custom fields, this will remove the None option from the list.
Rendering: This specifies how the content is to be rendered for text-based fields (for example, wiki renderer or simple text renderer for text fields).
A field configuration provides you with control over each individual field in your JIRA, including both built-in and custom fields. Since it is usually a good practice to re-use the same set of fields...
