Filtering issues and pull requests by assignees

Once you've assigned an issue or pull request to someone, you can find items based on who's working on them.

On GitHub Enterprise, navigate to the main page of the repository.
Under your repository name, click Issues or Pull requests.
In the upper-right corner, select the Assignee drop-down menu.
The Assignee drop-down menu lists everyone who has write access to your repository. Click the name of the person whose assigned items you want to see, or click Assigned to nobody to see which issues are unassigned.

To clear your filter selection, click Clear current search query, filters, and sorts.
