Project Issue Board
GitLab has Issue Boards, each list of an Issue Board is based on a label that exists in your issue tracker. The Issue Board will therefore match the state of your issue tracker in a user-friendly way.
Multiple Project Issue Boards
Large companies often have hundreds of different projects, all with different moving parts at the same time. GitLab Enterprise Edition allows for multiple Issue Boards for a single project so you can to plan, organize, and visualize a workflow for a feature or product release. Multiple Issue Boards are particularly useful for large projects with more than one team or in situations where a repository is used to host the code of multiple products.

Issue Board Label Lists
An Issue Board is based on its project's label structure, therefore, it applies the same descriptive labels to indicate placement on the board. GitLab issues can appear on multiple issues and they still have meaning without the context of a particular board.
Add Multiple Issues to Project Issue Board
From an Issue Board, you can add multiple issues to lists in the board by selecting one or more existing issues.
