The filters pane can help you find the file or list item you’re looking for. When you make a filter selection, items that don’t match are removed from the list shown on the page.
Note: Some functionality is introduced gradually to organizations that have opted in to the First Release program. If you're not enrolled in the First Release program, you may not see this feature.
Open the filters pane
Click the filter icon at the top right of your list or library to open the filter pane. The filters you see are based on the list items currently in view.
For document libraries, 3 default filters show: Modified, People and Type. You can narrow the list to recent files only. You can filter your view to files edited by one or more people. And, you can change your view to show files of one or more types, like Word documents and PowerPoint slides.
When you’ve filtered the list or library and want to go back to where you started, click the clear filter icon at the top right of the filter pane.
How the filters pane works together with column headers and views
The filters pane works together with SharePoint features you may already be familiar with like column headers and views. Filters selected in the column header menu also show on the filter pane. And, it works the same way in reverse. Selections made on the filter pane show in the column header filter selections.
Views allow you to save your filter selections.
