This script will make every list’s header sticky. This means that it will stick to the bottom of SharePoint’s ribbon when it would otherwise disappear behind it. Keeping the header visible at all times can greatly enhance the usability, especially of large lists.
The script supports the normal list view, fixed height lists, list in quick edit mode, grouped lists, and all kinds of system lists like the list on the permissions page or site features page.
The sticky headers keep their full functionality so you can use them so sort, filter, etc.
