Restrict sub-tasks by issue type

Atlassian Update – 6 March 2018 Hi everyone, Thank you for your interest in this issue. While this suggestion has gathered significant interest, we're unable to implement all of the excellent suggestions you make. We don't plan to work on this for the foreseeable future. This suggestion will be reviewed in about 12 months time, at which point we’ll consider whether we need to alter its status.  I understand this decision will be disappointing to everyone who voted for this issue. While we believe this suggestion would improve the product, after careful review of the most pressing needs of our customers, we've decided to prioritize other areas of the Jira Server roadmap, including: Performance and stability improvements Archiving projects for improved performance Optimising the use of custom fields Improving performance of boards Improving Jira notifications Allowing users to edit shared filters and dashboards Mobile app for Jira Server  We recommend checking out the following apps on the Atlassian Marketplace: Jira Misc Workflow Extensions Power Scripts for Jira Script Automation Issue Type Filters Workflow Essentials for Jira   For more context, check out our Community blog on  our renewed approach to highly voted Server suggestions for Jira and Confluence . Thanks again. Regards, Jira Server product management
