How do I assign multiple issues to a project in github

I cannot find an option for me to bulk select multiple issues and assign them to an project. I can only bulk assign labels and other stuff.

How do I add issues to GitHub projects?

You can add issue or pull request cards to your classic project by: Dragging cards from the Triage section in the sidebar. Typing the issue or pull request URL in a card. Searching for issues or pull requests in the classic project search sidebar.

How do I add multiple assignees in GitHub?

Assignees can be added and removed on the web UI by clicking on the assignees dropdown in the sidebar and adding multiple users.

How do I change the number of issues in GitHub?

It is not currently possible to change how Issues are displayed in this way on GitHub.com. The API does allow you to change how many issues are pulled, so you could write a script to interact with the API in that way to build a custom interface allowing you to get the information and customization that you want.

The quickest way I have found...

Projects -> [Your Project] -> + Add cards

(you can change the search filters to find any issues from here)

Click and drag is less intensive than clicking into each issue and assigning it but there should be a better way to do this
