Smart Checklist supports JQL as an approach for searching checklist items values and checklist progress.
If you set up "Checklists" (multi-line text field) and "Smart Checklist Progress" (single-line text field) which are both custom fields - you can easily apply all JQL search patterns.
- To search for issues with opened checklists (not all checklist items completed).
- Type in JQL: "Smart Checklist Progress" ~ "-Done"
- To search for issues with ALL completed checklists
- Type in JQL: "Smart Checklist Progress" ~ "Done"
