Behaviours give you more options to customize how fields in Jira behave, so you can show/hide additional fields when a particular option is selected. For example, you give users the option to select a checkbox when they do not know their SEN (Support Entitlement Number). You can set up a behaviour to show additional fields when this checkbox is selected, to collect the information required to identify them.Alternatively, you might want to use a behaviour to control what information certain users can edit or view. For example, as As a project manager, you may want full control over which issues go into a sprint. Using behaviours, you can make the Sprint field read-only for anyone except users in the Project Managers role, ensuring only project managers can add issues to sprints.
