Issues and pull requests can be filtered based on the milestone they're associated with. Once you've associated an issue or pull request with a milestone, you can find items based on their milestones.
Tip: If you'd rather filter issues and pull requests using the Search bar, you can use the milestone search syntax. For a milestone called My Milestone, the search syntax would be: milestone:"My Milestone"
.
To clear your filter selection, click Clear current search query, filters, and sorts.
On GitHub Enterprise, navigate to the main page of the repository.
