If you are using a “Dropdown” filter in a Quick Controller, the following option will be available:
If enabled, “Smart Dropdowns” will ensure that dropdown filters only provide meaningful suggestions i.e. suggestions matching with the current state of the Quick Controller.
Consider the following example:
Here, the “assignee” dropdown will only show users assigned to issues that are in the project “Quality” and have the priority “Medium”. On top of that, only assignees of issues with the “database” component will be shown, according to the configuration shown above.
Please also consider the following:
Smart dropdowns will not show all possible values, but instead only values that are actually used by the currently filtered issues. In the example above, this means that not all possible assignees of the project “Quality” will be shown, but instead only the users that are actually assigned to issues in this project.
Only the first 1000 filtered issues are used for smart dropdowns suggestions.
If no value is found, all possible values of the Jira instance will be shown as suggestions, as if the “Smart Dropdowns” option wasn’t enabled.
