The Advanced Issue Link app provides Jira with a new custom field that allows users to easily and quickly identify and select issues. You can even let users select issues for which they don’t have browse permissions.
In this custom field, the user can create and remove issue links depending on the options selected. In addition, the linked custom problem field can be used in JQL functions. After giving your custom field a name, the app offers two field types - Multiple Issue Picker and Single Issue Picker. Create one field and use it in different projects. You can add a desired JQL filter in the text field and select a screen in which you want the field to appear. Use the view templates option to describe how issues details are displayed.
