docs/data/reusables/projects/customize/slice-panel.md

You can slice your items by a field to view a list of the field values in a separate panel. When you click on a value in the slice panel, the current view will adjust to only show items with that value. The slice panel works with the current filter applied to your view.

{% note %}

Note: You cannot slice by title, reviewers, or linked pull requests.

{% endnote %}

{% data reusables.projects.open-view-menu %}

1. Click Slice by.
2. Click the field you want to slice by.
3. Optionally, to disable slicing, click {% octicon "x" aria-hidden="true" %} No slicing at the bottom of the list.

With the slice panel open, you can change the current field by using the menu at the top of the slice panel.
